500 - internal server error my API is not working

I make a crud with products
I send an http request to the /api/deleteProduct route with the product id to retrieve it on the server side and delete the product by its id
To create a product it works only the delete does not work
pages/newProduct.js :
useEffect(() => {
async function fetchData() {
const res = await axios.get('/api/products');
setProducts(res.data);
}
fetchData();
}, []);
const handleSubmit = async (event) => {
event.preventDefault();
const formData = new FormData();
formData.append('picture', picture);
formData.append('name', name);
formData.append('price', price);
formData.append('category', category);
formData.append('description', description);
try {
const res = await axios.post('/api/createProduct', formData);
console.log(res.data);
} catch (error) {
console.log(error);
}
};
const handleDelete = async (id) => {
try {
await axios.delete(`/api/deleteProduct?id=${id}`);
setProducts(products.filter(product => product._id !== id));
} catch (error) {
console.log(error);
}
};
api/deleteProduct.js :
import Product from '../../models/Products';
import { initMongoose } from '../../lib/mongoose';
initMongoose();
export const handleDelete = async (req, res) => {
if (req.method === 'DELETE'){
try {
const { id } = req.params
const product = await Product.findByIdAndRemove(id);
if (!product) {
return res.status(404).json({ message: 'Product not found' });
}
return res.status(200).json({ message: 'Product deleted successfully' });
} catch (error) {
console.log(error);
return res.status(500).json({ message: 'Database error' });
}
}};
I have a 500 error but no error in the server side console and the console.log is not showing like the file was not read

Based on the code you've shared, it seems that the problem may be with the way that the delete request is being handled on the frontend. Specifically, in this line:
await axios.delete("/api/deleteProduct", { params: { id } });
The delete request is supposed to receive the id of the product that should be deleted as a query parameter, but it is being passed as a request body.
Instead of passing it as a parameter, you should pass it as a query parameter by changing it to
await axios.delete(`/api/deleteProduct?id=${id}`);
Also, in your api/deleteProduct.js, you should change the following line:
const { id } = req.query;
to
const { id } = req.params;
Also, you should make sure that the server is running and that the api endpoint '/api/deleteProduct' is accessible and handling the request correctly.
For the last, make sure that the product model is imported and initialized correctly and the database connection is established.
Hope that it solves your problem or, at least, helps :))

I succeeded, I put this (server side):
const { id } = req. query;
and (client side):
await axios.delete(/api/deleteProduct?id=${id});
and I exported my function like this:
export default async function handleDelete(req, res) {

i try to send notification to specific device using firebase cloud function

i am building chat app with flutter and I try to send notification to specific device using the cloud function so when a user send message to his friend then his friend get notification with the message but I get that error
note : I don not have any knowledge with javascript or node js
Unhandled error Error: Value for argument "documentPath" is not a valid resource path. Path must be a non-empty string.

at /workspace/node_modules/firebase-functions/lib/common/providers/https.js:407:32
at processTicksAndRejections (node:internal/process/task_queues:96:5)
first I try to get the device token and save it to firebase
void getToken() async {
await fcm.getToken().then((value) {
tokens = value;
print('my token22 is $tokens');
saveToken(tokens: tokens);
});
}
void saveToken({String? tokens}) async {
FirebaseFirestore.instance.collection('userToken').doc(userphone).set({
'token': tokens,
});
}
then I try to call this token at index.js file at function function
const functions = require("firebase-functions");
const admin = require("firebase-admin");
admin.initializeApp();
exports.addMessage = functions.https.onCall(
(data, context) => {
const friendPhone = data.text;
const userDoc = admin
.firestore()
.collection("userToken")
.doc(friendPhone)
.get();
const deviceTokens = userDoc.data();
console.log(deviceTokens);
const title = data.title;
const body = data.body;
try {
if (deviceTokens) {
exports.myFunction = functions.firestore
.document("chats/{chatId}/messegeId/{messageId}")
.onWrite((snap, context) => {
console.log(snap.data());
admin.messaging().sendToDevice(deviceTokens,
{
notification: {title: title,
body: body,
clickAction: "FLUTTER_NOTIFICATION_CLICK",
},
});
});
}
} catch (error) {
console.log(error);
throw new functions.https.
HttpsError("invalid-argument", "some message");
}
}
);
after that I call the function at sendMessege button so that when the user send messgege it work
Future<void> writeMessage({
String? message,
String? title,
String? friendPhone,
}) async {
HttpsCallable callable =
FirebaseFunctions.instance.httpsCallable("addMessage");
final resp = await callable.call(<String, dynamic>{
"text": friendPhone,
"title": title,
"body": message,
});
print("result: ${resp.data}");
}

oare you sure that the path for the friendPhone is a valid path in firebase?
Is there maybe a spelling mistake in messageId?
document("chats/{chatId}/messegeId/{messageId}")
You wrote messegeId instead of messageId
Hope that helps.

How to mock Twilio using Jest and TypeScript for unit testing

I need your help to mock a twilio service which sends a message, using jest to mock the service
I have the next code:
import { SQSEvent } from "aws-lambda";
import { GetSecretValueResponse } from "aws-sdk/clients/secretsmanager";
export async function sendSms(event: SQSEvent, data: GetSecretValueResponse) {
const secrets = JSON.parse(data.SecretString);
const accountSid = secrets.TWILIO_ACCOUNT_SID;
const authToken = secrets.TWILIO_AUTH_TOKEN;
const twilioNumber = secrets.TWILIO_PHONE_NUMBER;
if (accountSid && authToken && twilioNumber) {
//Create a Twilio Client
const client = new Twilio(accountSid, authToken);
//Loop into al records of the event, every record is every message sent from Sqs
for (const record of event.Records) {
const body = JSON.parse(record.body);
const userNumber = "+" + body.number;
//SendMessage function
try {
const message = client.messages.create({
from: twilioNumber,
to: userNumber,
body: body.message,
});
return message;
} catch (error) {
return `Failed to send sms message. Error Code: ${error.errorCode} / Error Message: ${error.errorMessage}`;
}
}
} else {
return "You are missing one of the variables you need to send a message";
}
}
The I call this function from my index:
import { SQSEvent } from "aws-lambda";
import { sendSms } from "./services/sendSms/sendSms";
import { getSecret } from "./services/obtainSecrets/getSecret";
import { SecretsManager } from "aws-sdk";
export const lambdaHandler = async (event: SQSEvent) => {
try {
const obtainedSecret = await getSecret()
.then((credentials: SecretsManager.GetSecretValueResponse) => {
return credentials;
})
.catch(error => {
return error;
});
const response = sendSms(event, obtainedSecret)
.then(response => {
return response;
})
.catch(error => {
return error;
});
return {
message: "OK " + obtainedSecret + response,
code: 200,
};
} catch (error) {
throw new Error(error);
}
};
I have already make some tests, but them always makes a connection with Twilio api(requiring the real token, sid,etc), and I need to mock the Twilio service, so the function I call in my test.ts doesn't connects to internet.
import { Twilio } from "twilio";
import { MessageInstance } from "twilio/lib/rest/api/v2010/account/message";
import { sendSms } from "../../services/sendSms/sendSms";
//mock Twilio library and sendSms service
jest.mock("twilio");
jest.mock("../../services/sendSms/sendSms");
const smsMessageResultMock: Partial<MessageInstance> = {
status: "sent",
sid: "AC-lorem-ipsum",
errorCode: undefined,
errorMessage: undefined,
};
describe("SMS Service", () => {
describe("Send Message", () => {
it("Should fail", async () => {
// update smsMessageResultMock to simulate a faled response
const smsMessageMock = {
...smsMessageResultMock,
status: "failed",
errorCode: 123,
errorMessage: "lorem-ipsum",
};
// simulated response of secret management
let data = {
ARN: "arn:aws:secretsmanager:us-west-2:123456789012:secret:MyTestDatabaseSecret-a1b2c3",
Name: "MyTestDatabaseSecret",
SecretString:
'{"TWILIO_ACCOUNT_SID": "ACTWILIO_ACCOUNT_SID","TWILIO_AUTH_TOKEN": "TWILIO_AUTH_TOKEN","TWILIO_PHONE_NUMBER": "TWILIO_PHONE_NUMBER"}',
VersionId: "EXAMPLE1-90ab-cdef-fedc-ba987SECRET1",
VersionStages: ["AWSPREVIOUS"],
};
// simulated response of SqsEvent
let event = {
Records: [
{
messageId: "19dd0b57-b21e-4ac1-bd88-01bbb068cb78",
receiptHandle: "MessageReceiptHandle",
body: '{"message": "Hello world","number": "(506)88888888"}',
attributes: {
ApproximateReceiveCount: "1",
SentTimestamp: "1523232000000",
SenderId: "123456789012",
ApproximateFirstReceiveTimestamp: "1523232000001",
},
messageAttributes: {},
md5OfBody: "{{{md5_of_body}}}",
eventSource: "aws:sqs",
eventSourceARN: "arn:aws:sqs:us-east-1:123456789012:MyQueue",
awsRegion: "us-east-1",
},
],
};
// simulate tokens for Twilio
const accountSid = "ACfjhdskjfhdsiuy876hfijhfiudsh";
const authToken = "fjfuewfiuewfbodfiudfgifasdsad";
//create client with mocked Twilio
const client = new Twilio(accountSid, authToken);
//call messages.create of Twilio client, and give it the expected result created
client.messages.create = jest
.fn()
.mockResolvedValue({ ...smsMessageMock });
console.log(await sendSms(event, data));
//expectes the function sendSms(event, data) to throw an error
await expect(sendSms(event, data)).rejects.toThrowError(
`Failed to send sms message. Error Code: ${smsMessageMock.errorCode} / Error Message: ${smsMessageMock.errorMessage}`
);
});
});
});
(event and data are simulated responses of SqsEvent and GetSecretValueResponse)
The problem is that when I run the npm test it throws me an error of Twilio's authentication, an it is because I'm passing self created tokens.
Expected substring: "Failed to send sms message. Error Code: 123 / Error Message: lorem-ipsum"
Received message: "Authentication Error - invalid username"
at success (node_modules/twilio/lib/base/Version.js:135:15)
at Promise_then_fulfilled (node_modules/q/q.js:766:44)
at Promise_done_fulfilled (node_modules/q/q.js:835:31)
at Fulfilled_dispatch [as dispatch] (node_modules/q/q.js:1229:9)
at Pending_become_eachMessage_task (node_modules/q/q.js:1369:30)
at RawTask.Object.<anonymous>.RawTask.call (node_modules/asap/asap.js:40:19)
at flush (node_modules/asap/raw.js:50:29)
So what I suppose is that the test is connecting to internet and calling Twilio's api.
I appreciate if you could help me.

I think what you want to do is mock the class returned by the module, using jest.mock('twilio', mockImplementation) and in mockImplementation return a function to act as a constructor that will take your account SID and auth token arguments and then return a mockClient implementation, which in this case needs to return an object which has a messages property, which in turn is an object with a create property that is a mock function.
It's probably easier to just show the code.
const mockClient = {
messages: {
create: jest.fn().mockResolvedValue({ ...smsMessageMock });
}
};
jest.mock("twilio", () => {
return function(accountSid, authToken) {
return mockClient;
}
});

Javascript SlackBot postMessage function is spamming messages

I am trying to set up a slack bot using javascript and a few helpful libraries.
All it does is run a postMessageToChannel Method when a user of the channel mentions a certain keyword " help"
My issue is when the runHelp() function is called it doesn't just post one message to the slack #channel but many. Maybe i am missing something here that someone can help me figure out.
Thanks,
Here's the js:
const SlackBot = require('slackbots');
const axios = require('axios')
const dotenv = require('dotenv')
dotenv.config()
const bot = new SlackBot({
token: `${process.env.BOT_TOKEN}`,
name: 'helpit-bot'
});
// Start Handler
bot.on('start', () => {
const params = {
icon_emoji: ':nerd_face:'
}
bot.postMessageToChannel('slack-bot', 'HELP IS ON THE WAY', params);
})
// Error Handler
bot.on('error', (err) => {
console.log(err);
});
// Message Handler
bot.on('message', (data) => {
if(data.type !== 'message') {
return;
}
handleMessage(data.text);
return;
})
// Response Handler
function handleMessage(message) {
if(message.includes(' help')) {
runHelp();
} else {
// Run something else
}
}
// Show Help
function runHelp() {
const params = {
icon_emoji: ':question:'
}
bot.postMessageToChannel('slack-bot', 'This is an automated help message', params);
}
Result:

Created an infinite loop because "This is an automated help message" includes the text "help" which triggers the bot. -.-

Creating an application that will listen to a telegram channel

First of all please note that this is not about creating a bot.
My goal is to create an application that will simply listen to any number of telegram channels that the account I will provide it with is subscribed to and retrieve all messages sent to those channels (as if I was a normal user). My guess is that I will need to
Authenticate myself using my account's phone number
Be able to setup a callback listener either per channel or a general listener for all incoming messages
I've been looking around the telegram api for a couple of days now and I am extremely confused as to how it works. After giving up on it, I started looking at readymade implementations, mostly for NodeJS but was still not able to find a concrete solution. I'm testing some things with the telegram-js api but running it directly using node didn't work. Does it need to run in a browser? Is there any more streamlined approach to this? Preferably something with good documentation.
PS: I'm fluent in Java and Javascript mostly so I've prioritized libraries based on those languages.
EDIT:
Here is the code that I've written (essentially copied an example)
var { Telegram } = require("../libs/telegram");
var TypeLanguage = require("telegram-tl-node") ;
var MTProto = require("telegram-mt-node");
var schema = require("../libs/api-schema.json");
const APP_ID = "111111";
const APP_HASH = "fb6da8f6abdf876abd6a9d7bf6";
const SERVER = { host: "111.111.111.11", port: "443" };
const config = {
id: APP_ID,
hash: APP_HASH,
version: '0.0.1',
lang_code: 'en',
authKey: null
};
let telegram = new Telegram(MTProto, TypeLanguage);
telegram.useSchema(schema);
addPublicKeys(telegram);
let connection = new MTProto.net.HttpConnection(SERVER);
let client = telegram.createClient();
client.setConnection(connection);
connection.connect(function() {
let ready = client.setup(config);
ready.then(function(client) {
// it never resolves this promise
function callback(response) {
console.log(response);
}
client.callApi("help.getConfig").then(callback, callback);
});
});
It uses those 2 libs:
telegram-mt-node
telegram-tl-node

Late answer but might help others.
You can utilize mtproto-core to authenticate with a regular telegram account and listen to updates (or do anything you can with telegram clients, really)
Here is a sample script I've written that listens to new messages from channels/supergroups the user is subscribed to:
const { MTProto, getSRPParams } = require('#mtproto/core');
const prompts = require('prompts');
const api_id = ...; // insert api_id here
const api_hash = ' ... '; // insert api_hash here
async function getPhone() {
return (await prompts({
type: 'text',
name: 'phone',
message: 'Enter your phone number:'
})).phone
}
async function getCode() {
// you can implement your code fetching strategy here
return (await prompts({
type: 'text',
name: 'code',
message: 'Enter the code sent:',
})).code
}
async function getPassword() {
return (await prompts({
type: 'text',
name: 'password',
message: 'Enter Password:',
})).password
}
const mtproto = new MTProto({
api_id,
api_hash,
});
function startListener() {
console.log('[+] starting listener')
mtproto.updates.on('updates', ({ updates }) => {
const newChannelMessages = updates.filter((update) => update._ === 'updateNewChannelMessage').map(({ message }) => message) // filter `updateNewChannelMessage` types only and extract the 'message' object
for (const message of newChannelMessages) {
// printing new channel messages
console.log(`[${message.to_id.channel_id}] ${message.message}`)
}
});
}
// checking authentication status
mtproto
.call('users.getFullUser', {
id: {
_: 'inputUserSelf',
},
})
.then(startListener) // means the user is logged in -> so start the listener
.catch(async error => {
// The user is not logged in
console.log('[+] You must log in')
const phone_number = await getPhone()
mtproto.call('auth.sendCode', {
phone_number: phone_number,
settings: {
_: 'codeSettings',
},
})
.catch(error => {
if (error.error_message.includes('_MIGRATE_')) {
const [type, nextDcId] = error.error_message.split('_MIGRATE_');
mtproto.setDefaultDc(+nextDcId);
return sendCode(phone_number);
}
})
.then(async result => {
return mtproto.call('auth.signIn', {
phone_code: await getCode(),
phone_number: phone_number,
phone_code_hash: result.phone_code_hash,
});
})
.catch(error => {
if (error.error_message === 'SESSION_PASSWORD_NEEDED') {
return mtproto.call('account.getPassword').then(async result => {
const { srp_id, current_algo, srp_B } = result;
const { salt1, salt2, g, p } = current_algo;
const { A, M1 } = await getSRPParams({
g,
p,
salt1,
salt2,
gB: srp_B,
password: await getPassword(),
});
return mtproto.call('auth.checkPassword', {
password: {
_: 'inputCheckPasswordSRP',
srp_id,
A,
M1,
},
});
});
}
})
.then(result => {
console.log('[+] successfully authenticated');
// start listener since the user has logged in now
startListener()
});
})
You can find the values for api_id and api_hash from https://my.telegram.org.
On the first run the script prompts the user for phone_number, code, and password.
[+] You must log in
√ Enter your phone number: ... <phone_number>
√ Enter the code sent: ... <code>
√ Enter Password: ... <2FA password>
and after the authentication is over
a sample run outputs:
[+] starting listener
[13820XXXXX] Ja
[13820XXXXX] Bis bald guys��
[13820XXXXX] Ja. �
[13820XXXXX] Bis später
[13820XXXXX] Jaaa�
The way I've checked the authentication status was taken from here.
Alternative libraries worth checking out that are active the time of writing (and can be used to create the same behavior with): Airgram (tdlib) and GramJs

I used gram.js library and essentially did this:
import { TelegramClient } from 'telegram'
TelegramClient().addEventHandler(handler, { chats: [1234567890] })
The bot does NOT need to be a member of the channel you want to listen to.
My code runs as a Node.js app.
You need to first create a token by talking to #BotFather with Telegram.

here is my working code by using gramjs and its purely on nodejs.
Getting all the messages from all the channels without any delay's.
import {
TelegramClient
} from "telegram";
import {
NewMessage,
NewMessageEvent
} from "telegram/events";
import {
StringSession
} from "telegram/sessions";
const input = require("input");
const apiId = 1233456677;
const apiHash = "xxxxxxxxxxxxxxxxx";
let stringSession = new StringSession("xxxxxxxxxxxxxxxxx");
(async() => {
console.log("Loading interactive example...");
const client = new TelegramClient(stringSession, apiId, apiHash, {
connectionRetries: 5,
});
await client.start({
phoneNumber: async() => await input.text("Please enter your number: "),
password: async() => await input.text("Please enter your password: "),
phoneCode: async() =>
await input.text("Please enter the code you received: "),
onError: (err) => console.log(err),
});
console.log("You should now be connected.");
const session: any = client.session.save();
stringSession = new StringSession(session); // Save this string to avoid logging in again - specially in nodemon
console.log(client.session.save()); // --> you can also copy this session from your console once you get it and paste it in line number 8 - new StringSession("XXXXXXXXXXXXXX")
// once you saved add the JWT Token on line no. 8 as mention above next time you will getting directly connected.
await client.sendMessage("me", {
message: "Hello!"
});
async function handler(event: NewMessageEvent) {
console.log("[newmessage]", event);
}
client.addEventHandler(handler, new NewMessage({}));
})();
Note - Ignore the "Run Code Snippet" as found it best way to add whole code instead of formatting.

You can use the gram.js library in the following way:
Install these:
npm install properties-reader
npm install telegram
npm install input
Then get your apiId and apiHash from Telegram Auth in the App Configuration section.
Create a file config.properties with a content similar to that:
[telegram]
apiId=12345678
apiHash=12345678901234567890123456789012
Inside of your nodejs code you can listen to a specific chat like this (see chatId inside of the code below):
const PropertiesReader = require('properties-reader');
const configs = PropertiesReader('config.properties');
getProp = (bundle, key) => {return configs.get(`${bundle}.${key}`);}
const { TelegramClient } = require("telegram");
const { StoreSession } = require("telegram/sessions");
const { NewMessage } = require("telegram/events");
const { EditedMessage } = require("telegram/events/EditedMessage");
const input = require("input");
const apiId = getProp("telegram", "apiId")
const apiHash = getProp("telegram", "apiHash")
const storeSession = new StoreSession("telegram_session"); // see: https://painor.gitbook.io/gramjs/getting-started/authorization#store-session
(async () => {
console.log("Loading interactive example...");
const client = new TelegramClient(storeSession, apiId, apiHash, {
connectionRetries: 5,
});
await client.start({
phoneNumber: async () => await input.text("Please enter your number: "),
password: async () => await input.text("Please enter your password: "),
phoneCode: async () =>
await input.text("Please enter the code you received: "),
onError: (err) => console.log(err),
});
console.log("You should now be connected.");
client.session.save(); // Save the session to avoid logging in again
async function eventPrint(event) {
// see 'node_modules/telegram/tl/custom/message.d.ts'
const message = event.message
const isNew = message.editDate === undefined
const text = message.text
const date = new Date(message.date*1000)
console.log(`The message is ${isNew ? 'new' : 'an update'}`)
console.log(`The text is: ${text}`)
console.log(`The date is: ${date}`)
}
// to get the chatId:
// option 1: open telegram on a web browser, go to the chat, and look the url in the address bar
// option 2: open telegram app, copy link to any message, it should be something like: https://t.me/c/1234567890/12345, the first number after "/c/" is the chatId
const chatId = 1234567890
client.addEventHandler(eventPrint, new NewMessage({ chats: [chatId] }));
client.addEventHandler(eventPrint, new EditedMessage({ chats: [chatId] }));
})();
