How to get the author from the "channelDelete" event Discord.js v13

I'm trying to create an anti-crash function, but got confused at the moment that the channel does not return the author. How can I get the author in another way?
I tried to connect to AuditLogEvent, but it didn't work
My code:
const { AuditLogEvent } = requier('discord.js')
const usersMap = new Map();
const LIMIT = 3;
const TIMES = 10000
bot.rest.on('channelDelete', async channel => {
const fetchedLogs = await channel.guild.fetchAuditLogs({
limit: 1,
type: AuditLogEvent.ChannelDelete,
})
const deletionLog = fetchedLogs.entries.first();
const { executor, target } = deletionLog
if(channel.guild.id != "940990129307263046") return
if(usersMap.has(executor.id)) {
const userData = usersMap.get(executor.id);
const { lastDelete, timer } = userData;
let deleteCount = userData.deleteCount;
const tim = channel.createdTimestamp - lastDelete.createdTimestamp
if(tim > TIMES) {
usersMap.delete(executor.id)
} else {
++deleteCount;
if(parseInt(deleteCount) === LIMIT) {
executor.ban()
}
}
}
})

Firebase cloud function uploading data to the cloud firebase deletes the data without any reason

Hello so a little bit of background.
I created a function in JS that fetches some data(multiple objects that can change in number every time I fetch the data ad example : fetch1: I get 3 obj | fetch2: I get 1 obj, I CAN NOT GET 0 obj ) from a website every minute, processes that data, and then sends it to the cloud firestore. The problem is that after the upload of the data, the doc and the collection get deleted without any reason at all and I don't understand what is happening.
I tried to search online but I could not find a fix.
Can anyone give me a hint of what is happening ?
This is the function in JS
import functions = require("firebase-functions");
import admin = require("firebase-admin");
admin.initializeApp();
const database = admin.firestore();
import https = require("https");
let finalData: { [x: string]: any; }[] = [];
const page = 1;
const fiat = "";
const tradeType = "";
const asset = "";
const payTypes = [""];
const baseObj = {
page,
rows: ,
publisherType: ,
asset,
tradeType,
fiat,
payTypes,
};
const stringData = JSON.stringify(baseObj);
const options = {
hostname: "",
port: ,
path: "",
method: "",
headers: {
"Content-Type": "application/json",
"Content-Length": stringData.length,
},
};
const req = https.request(options, (res: any) => {
finalData = [];
let output = "";
res.on("data", (d: string) => {
output += d;
});
res.on("end", () => {
try {
const jsonOuput = JSON.parse(output);
const allData = jsonOuput["data"];
for (let i = 0; i < allData.length; i++) {
let payTypesz = "";
for (let y = 0; y < allData[i]["adv"]["tradeMethods"].length; y++) {
payTypesz += allData[i]["adv"]["tradeMethods"][y]["payType"];
if (y < allData[i]["adv"]["tradeMethods"].length - 1) {
payTypesz += ", ";
}
}
const obj = {
tradeType: allData[i]["adv"]["tradeType"],
asset: allData[i]["adv"]["asset"],
fiatUnit: allData[i]["adv"]["fiatUnit"],
price: allData[i]["adv"]["price"],
surplusAmount: allData[i]["adv"]["surplusAmount"],
maxSingleTransAmount: allData[i]["adv"]["maxSingleTransAmount"],
minSingleTransAmount: allData[i]["adv"]["minSingleTransAmount"],
nickName: allData[i]["advertiser"]["nickName"],
monthOrderCount: allData[i]["advertiser"]["monthOrderCount"],
monthFinishRate: allData[i]["advertiser"]["monthFinishRate"],
advConfirmTime: allData[i]["advertiser"]["advConfirmTime"],
payTypes: payTypesz,
position: 0,
};
finalData.push(obj);
}
console.log(finalData);
} catch (e) {
console.log(e);
}
});
});
exports.scheduledFunction = functions.pubsub
.schedule("* * * * *")
.onRun((context: any) => {
req.write(stringData);
req.end();
for (let i = 0; i < finalData.length; i++) {
database.doc("/$i")
.set({
"tradeType": finalData[i]["tradeType"],
"asset": finalData[i]["asset"],
"fiatUnit": finalData[i]["fiatUnit"],
"price": finalData[i]["price"],
"surplusAmount": finalData[i]["surplusAmount"],
"maxSingleTransAmount": finalData[i]["maxSingleTransAmount"],
"minSingleTransAmount": finalData[i]["minSingleTransAmount"],
"nickName": finalData[i]["nickName"],
"monthOrderCount": finalData[i]["monthOrderCount"],
"monthFinishRate": finalData[i]["monthFinishRate"],
"advConfirmTime": finalData[i]["advConfirmTime"],
"payTypes": finalData[i]["payTypes"],
"position": finalData[i]["position"],
});
}
return console.log("Succes Upload of the data ");
});
// # sourceMappingURL=index.js.map
This is the setup of the DB.

By default https for Node.js does not return Promises, therefore it can be cumbersome to correctly manage the life cycle of your Cloud Function.
I would suggest you use the axios library and refactor your code as follows, using a batched write to write to Firestore:
exports.scheduledFunction = functions.pubsub
.schedule("* * * * *")
.onRun(async (context: any) => { // <=== See async keyword here
try {
const httpCallResponse = await axios.get(...); // I let you adapt the code, including the URL to call, according to the axios doc
const finalData = ... // Again, it's up to you to work out the value based on httpCallResponse
const batch = database.batch();
for (let i = 0; i < finalData.length; i++) {
batch.set(database.doc(i.toString(10)),
{
"tradeType": finalData[i]["tradeType"],
"asset": finalData[i]["asset"],
"fiatUnit": finalData[i]["fiatUnit"],
"price": finalData[i]["price"],
"surplusAmount": finalData[i]["surplusAmount"],
"maxSingleTransAmount": finalData[i]["maxSingleTransAmount"],
"minSingleTransAmount": finalData[i]["minSingleTransAmount"],
"nickName": finalData[i]["nickName"],
"monthOrderCount": finalData[i]["monthOrderCount"],
"monthFinishRate": finalData[i]["monthFinishRate"],
"advConfirmTime": finalData[i]["advConfirmTime"],
"payTypes": finalData[i]["payTypes"],
"position": finalData[i]["position"],
});
}
await batch.commit();
console.log("Succes Upload of the data ");
return null;
} catch (error) {
console.log(error);
return true;
}
});
Extra Note: Note that with your code you create monotonically increasing IDs and that could be a problem.

NodeJS script not actioning with async/await

Cannot figure out why the below script won't run. It is likely the script is not going to do what I want but using
node ./contentful/contentful-assets.js
in the terminal, it does nothing - No errors, nothing logged for me to even start debugging. However, if I remove async it will attempt the script and shoot back an error.
./contentful/contentful-assets.js
const contentful = require('contentful-management');
const iterator = require('make-iterator');
const assets = require('./assetObject.js');
async resolve => {
console.log('Creating Contentful client');
const client = contentful.createClient({
accessToken: 'token',
logHandler: (level, data) => console.log(`${level} | ${data}`)
});
const iterableAssets = iterator(assets);
const space = await client.getSpace('space');
const environment = await space.getEnvironment('enviroment');
const cmsAssets = [];
const assetProcessingTimes = [];
const inProcess = new Map();
let processedAssetsCounter = 0;
const createAndPublishSingleAsset = async ({ asset, done, index }) => {
if (done) {
if (inProcess.size > 0) return false;
return resolve(cmsAssets);
}
const start = Date.now();
const id = '' + start + Math.round(Math.random() * 100);
inProcess.set(id, true);
let cmsAsset;
try {
cmsAsset = await environment.createAssetWithId(asset.postId, {
fields: {
title: {
'en-US': asset.title
},
description: {
'en-US': asset.description
},
file: {
'en-US': {
contentType: 'image/jpg',
fileName: asset.filename,
upload: asset.link
}
}
}
});
} catch (e) {
console.log(`Asset "${asset.title}" failed to create, retrying...`);
createAndPublishSingleAsset({
asset,
done,
index
});
}
try {
const processedCMSAsset = await cmsAsset.processForAllLocales();
const publishedCMSAsset = await processedCMSAsset.publish();
cmsAssets.push(publishedCMSAsset);
assetProcessingTimes.push((Date.now() - start) / 1000);
inProcess.clear(id);
const eta = Math.floor(
assetProcessingTimes.reduce((a, b) => a + b, 0) /
assetProcessingTimes.length *
(assets.length - index) /
60
);
processedAssetsCounter += 1;
console.log(
`Processed asset ${processedAssetsCounter}/${assets.length} - eta: ${eta}m`
);
createAndPublishSingleAsset(iterableAssets.next());
} catch (e) {
console.log(`Asset "${asset.title}" failed to process, retrying...`);
await cmsAsset.delete();
createAndPublishSingleAsset({
asset,
done,
index
});
}
};
console.log('Starting to create assets');
createAndPublishSingleAsset(iterableAssets.next());
createAndPublishSingleAsset(iterableAssets.next());
createAndPublishSingleAsset(iterableAssets.next());
};
assetObject.js
[
{
link: 'https://example.com/example1.jpg',
title: 'Example 1',
description: 'Description of example 1',
postId: '1234567890',
filename: 'example1.jpeg'
}, ... // Many more
]
What have I missed here?

I fear that you are not calling the function, could you try, the following?
const contentful = require('contentful-management');
const iterator = require('make-iterator');
const assets = require('./assetObject.js');
const doWork = async resolve => {
console.log('Creating Contentful client');
...
}
doWork();
You are just declaring a function that is async and does all of the code defined, but you are not actually calling it.

In this code snippet you are declaring a function, but never invoking it:
//declaring an async function, with "resolve" as the argument
async resolve => {
//function definition
}
In order to be able to later reference the function to invoke you can assign it to const/let/etc.:
const createAssets = async resolve => { }
//now, invoke
createAssets()

How can I update more than 500 docs in Firestore using Batch?

I'm trying to update a field timestamp with the Firestore admin timestamp in a collection with more than 500 docs.
const batch = db.batch();
const serverTimestamp = admin.firestore.FieldValue.serverTimestamp();
db
.collection('My Collection')
.get()
.then((docs) => {
serverTimestamp,
}, {
merge: true,
})
.then(() => res.send('All docs updated'))
.catch(console.error);
This throws an error
{ Error: 3 INVALID_ARGUMENT: cannot write more than 500 entities in a single call
at Object.exports.createStatusError (C:\Users\Growthfile\Desktop\cf-test\functions\node_modules\grpc\src\common.js:87:15)

details: 'cannot write more than 500 entities in a single call' }
Is there a way that I can write a recursive method which creates a batch object updating a batch of 500 docs one by one until all the docs are updated.
From the docs I know that delete operation is possible with the recursive approach as mentioned here:
https://firebase.google.com/docs/firestore/manage-data/delete-data#collections
But, for updating, I'm not sure how to end the execution since the docs are not being deleted.

I also ran into the problem to update more than 500 documents inside a Firestore collection. And i would like to share how i solved this problem.
I use cloud functions to update my collection inside Firestore but this should also work on client side code.
The solution counts every operation which is made to the batch and after the limit is reached a new batch is created and pushed to the batchArray.
After all updates are completed the code loops through the batchArray and commits every batch which is inside the array.
It is important to count every operation set(), update(), delete() which is made to the batch because they all count to the 500 operation limit.
const documentSnapshotArray = await firestore.collection('my-collection').get();
const batchArray = [];
batchArray.push(firestore.batch());
let operationCounter = 0;
let batchIndex = 0;
documentSnapshotArray.forEach(documentSnapshot => {
const documentData = documentSnapshot.data();
// update document data here...
batchArray[batchIndex].update(documentSnapshot.ref, documentData);
operationCounter++;
if (operationCounter === 499) {
batchArray.push(firestore.batch());
batchIndex++;
operationCounter = 0;
}
});
batchArray.forEach(async batch => await batch.commit());
return;

I liked this simple solution:
const users = await db.collection('users').get()
const batches = _.chunk(users.docs, 500).map(userDocs => {
const batch = db.batch()
userDocs.forEach(doc => {
batch.set(doc.ref, { field: 'myNewValue' }, { merge: true })
})
return batch.commit()
})
await Promise.all(batches)
Just remember to add import * as _ from "lodash" at the top. Based on this answer.

You can use default BulkWriter. This method used 500/50/5 rule.
Example:
let bulkWriter = firestore.bulkWriter();
bulkWriter.create(documentRef, {foo: 'bar'});
bulkWriter.update(documentRef2, {foo: 'bar'});
bulkWriter.delete(documentRef3);
await close().then(() => {
console.log('Executed all writes');
});

As mentioned above, #Sebastian's answer is good and I upvoted that too. Although faced an issue while updating 25000+ documents in one go.
The tweak to logic is as below.
console.log(`Updating documents...`);
let collectionRef = db.collection('cities');
try {
let batch = db.batch();
const documentSnapshotArray = await collectionRef.get();
const records = documentSnapshotArray.docs;
const index = documentSnapshotArray.size;
console.log(`TOTAL SIZE=====${index}`);
for (let i=0; i < index; i++) {
const docRef = records[i].ref;
// YOUR UPDATES
batch.update(docRef, {isDeleted: false});
if ((i + 1) % 499 === 0) {
await batch.commit();
batch = db.batch();
}
}
// For committing final batch
if (!(index % 499) == 0) {
await batch.commit();
}
console.log('write completed');
} catch (error) {
console.error(`updateWorkers() errored out : ${error.stack}`);
reject(error);
}

Explanations given on previous comments already explain the issue.
I'm sharing the final code that I built and worked for me, since I needed something that worked in a more decoupled manner, instead of the way that most of the solutions presented above do.
import { FireDb } from "#services/firebase"; // = firebase.firestore();
type TDocRef = FirebaseFirestore.DocumentReference;
type TDocData = FirebaseFirestore.DocumentData;
let fireBatches = [FireDb.batch()];
let batchSizes = [0];
let batchIdxToUse = 0;
export default class FirebaseUtil {
static addBatchOperation(
operation: "create",
ref: TDocRef,
data: TDocData
): void;
static addBatchOperation(
operation: "update",
ref: TDocRef,
data: TDocData,
precondition?: FirebaseFirestore.Precondition
): void;
static addBatchOperation(
operation: "set",
ref: TDocRef,
data: TDocData,
setOpts?: FirebaseFirestore.SetOptions
): void;
static addBatchOperation(
operation: "create" | "update" | "set",
ref: TDocRef,
data: TDocData,
opts?: FirebaseFirestore.Precondition | FirebaseFirestore.SetOptions
): void {
// Lines below make sure we stay below the limit of 500 writes per
// batch
if (batchSizes[batchIdxToUse] === 500) {
fireBatches.push(FireDb.batch());
batchSizes.push(0);
batchIdxToUse++;
}
batchSizes[batchIdxToUse]++;
const batchArgs: [TDocRef, TDocData] = [ref, data];
if (opts) batchArgs.push(opts);
switch (operation) {
// Specific case for "set" is required because of some weird TS
// glitch that doesn't allow me to use the arg "operation" to
// call the function
case "set":
fireBatches[batchIdxToUse].set(...batchArgs);
break;
default:
fireBatches[batchIdxToUse][operation](...batchArgs);
break;
}
}
public static async runBatchOperations() {
// The lines below clear the globally available batches so we
// don't run them twice if we call this function more than once
const currentBatches = [...fireBatches];
fireBatches = [FireDb.batch()];
batchSizes = [0];
batchIdxToUse = 0;
await Promise.all(currentBatches.map((batch) => batch.commit()));
}
}

Based on all the above answers, I put together the following pieces of code that one can put into a module in JavaScript back-end and front-end to easily use Firestore batch writes, without worrying about the 500 writes limit.
Back-end (Node.js)
// The Firebase Admin SDK to access Firestore.

console.log({ err });
const errString = err.toString();

errString.includes("Error: 13 INTERNAL: Received RST_STREAM") ||
errString.includes("Error: 4 DEADLINE_EXCEEDED: Deadline exceeded")
);
};

// How many transactions/batchWrites out of 500 so far.
// I wrote the following functions to easily use batchWrites wthout worrying about the 500 limit.

No citations or documentation, this code i invented by myself and for me it worked and looks clean, and simple for read and usage. If some one like it, then can use it too.
Better make autotest becose code use private var _ops wich can be changed after packages upgrade. Forexample in old versions its can be _mutations
async function commitBatch(batch) {
const MAX_OPERATIONS_PER_COMMIT = 500;
while (batch._ops.length > MAX_OPERATIONS_PER_COMMIT) {
const batchPart = admin.firestore().batch();
batchPart._ops = batch._ops.splice(0, MAX_OPERATIONS_PER_COMMIT - 1);
await batchPart.commit();
}
await batch.commit();
}
Usage:
const batch = admin.firestore().batch();
batch.delete(someRef);
batch.update(someRef);
...
await commitBatch(batch);

Simple solution
Just fire twice ?
my array is "resultsFinal"
I fire batch once with a limit of 490 , and second with a limit of the lenght of the array ( results.lenght)
Works fine for me :)
How you check it ?
You go to firebase and delete your collection , firebase say you have delete XXX docs , same as the lenght of your array ? Ok so you are good to go
async function quickstart(results) {
// we get results in parameter for get the data inside quickstart function
const resultsFinal = results;
// console.log(resultsFinal.length);
let batch = firestore.batch();
// limit of firebase is 500 requests per transaction/batch/send
for (i = 0; i < 490; i++) {
const doc = firestore.collection('testMore490').doc();
const object = resultsFinal[i];
batch.set(doc, object);
}
await batch.commit();
// const batchTwo = firestore.batch();
batch = firestore.batch();
for (i = 491; i < 776; i++) {
const objectPartTwo = resultsFinal[i];
const doc = firestore.collection('testMore490').doc();
batch.set(doc, objectPartTwo);
}
await batch.commit();
}

Unexpected token o in JSON: How to fix?

I'm trying to save member data as JSON, but it is not working. I'm using discord.js framework.
I have searched Stack Overflow and many other sites, but I can't find a solution.
Here's the code snippet:
const user = message.guild.members.get(message.mentions.users.first().id);
const file = (user.id + ".json");
const content = {
"name": user.username,
"isFlagged": false,
"punishments": 1,
"id": user.id,
"discrim": user.discriminator
};
var B = content.toString();
fs.writeFileIfNotExist(file, B, function(err, existed) {
if (err) {
console.log(err)
} else {
console.log('file created sucessfuly!')
}
});
let points = JSON.parse(fs.readFileSync('./' + user.id + '.json'));
points.isFlagged = false;
points.punishments = points.punishments + 1;

As, CRice notes, calling Object.prototype.toString on an object created from a literal and not shadowing toString with an implementation returning a JSON formatted string, will return the string "[object Object"] which is not what you want.
This is demonstrated by the following snippet:
const content = {
name: 'John Smith',
isFlagged: false,
punishments: 1,
id: 5,
discrim: Symbol()
};
const b = content.toString();
console.log(b);
So first, change your code as follows
const content = {
name: 'John Smith',
isFlagged: false,
punishments: 1,
id: 5,
discrim: Symbol()
};
const b = JSON.stringify(content);
console.log(b);
Lastly, consider rewriting your program to cleanly and consistently leverage asynchronous IO and improve your naming patterns to follow established JavaScript conventions.
const promisify = require('util.promisify');
const fs = require('fs');
const exists = promisify(fs.exists);
const writeFile = promisify(fs.writeFile);
const readFile = promisify(fs.readFile);
const user = message.guild.members.get(message.mentions.users.first().id);
const file = `${user.id}.json`;
const content = {
name: user.username,
isFlagged: false,
punishments: 1,
id: user.id,
