I am trying to host a discord bot on my ubuntu server.
Everything was working but for some reason it just stopped working and it shows the same error all the time, no matter what i change.
const Discord = require('discord.js');
const client = new Discord.Client({intents: ["MessageContent"]});
client.login("My bots token")
console.log(client);
client.on('message', message => {
if (message.content === '!hello') {
message.channel.send('Nazdar!');
}
})
client.once('ready', () => {
console.log('Ready!');
})
The error message:

I tried changing all forms of uppercase or lowercase characters, but still the same issue. Thanks for every help!!

Your import is incorrect here:
const {web3js, myAccount} = require ('./utils')
It should be:
const web3js = new Web3(Web3.givenProvider || "ws://localhost:8545");
I am new to nodejs and trying to write this web scraper where I am getting the following errors. It asks to return promise however I tried but nothing works out. Not sure if I am using the right packages. Promises in async is quite difficult to understand for me at this point. Any explanation along with the code will be really apprciated.

Use for of instead of in. in will iterate over the keys and of over the values.
for(let web_url in web_urls){
the automatic reconnection function natively embedded in mongoose does not work on my project.
I actually receive a return in error but it does not start again after the X seconds that I configured.
Beyond whether the credentials are correct or not, I expect mongoose to try to log in every X seconds (and therefore send me a log each time) but it is not
Here is the doc in question: https://mongoosejs.com/docs/connections.html#options
Here is my code:
import mongoose from "mongoose"
const options = {
dbName: "testbdd",
pass: "qwe",
user: "alex",
useNewUrlParser: true,
serverSelectionTimeoutMS: 1000,
heartbeatFrequencyMS: 1000,
useUnifiedTopology: true
}
const uri = `mongodb://localhost/`
mongoose.connection.on('disconnected', function () {
console.log('Mongo db disconnected!');
});
mongoose.connect(uri, options).then(() => {
console.log('First Mongo db connexion success !')
}).catch((error) => {
console.log('First Mongo db connexion fail !')
console.log(error)
})
Here is the return when I run the node server:

Those options should work well, no ?

I am really lost. I doubt it's the mongoose code that doesn't work, it's necessarily my implementation.
Can you help me ?
This is the intended behavior of the mongodb driver
https://jira.mongodb.org/browse/NODE-834?focusedCommentId=1412582&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-1412582
The driver will fail on first connect if it cannot connect to the host. This is by design to ensure quick failure on unreachable hosts. Reconnect behavior only kicks in once the driver has performed the initial connect.
I need help...
So, I have this code
var express = require('express');
var app = express();
//Sites
// Landingpage CourseWorkers ----------------------------------------
app_courseworkers = require('./sites/app')
app_https_courseworkers = (req, response) => response.redirect("https://courseworkers.com")
But when I run it on the server I get the message:
0|index | TypeError: response.redirect is not a function
0|index | at Object.app_https_courseworkers [as handler] (/var/www/html/courseworkers/index.js:9:55)

0|index | at HTTPParser.parserOnHeadersComplete (_http_common.js:115:23)
Can anyone point out what I'm doing wrong?
Note: Running in localhost it goes normally
If you are trying to redirect to an external URL when someone goes to a specific URL on your site, try this:
app.get("/course", (req, res) => {
res.redirect("https://courseworkers.com");
});
My guess is, you are trying to call app_https_courseworkers(req, response), but you aren't actually passing in a valid response object.
