I use puppeteer-core with chrome-linux from https://storage.googleapis.com/chromium-browser-snapshots/Linux_x64/1095492/chrome-linux.zip.
this is my project:
project directory
// this is index.js
const puppeteer = require('puppeteer-core');
(async () => {
const browser = await puppeteer.launch({ headless: true, executablePath: './chrome-linux/chrome', args: ['--no-sandbox'] });
const page = await browser.newPage();
await page.goto('https://www.baidu.com/');
// Set screen size
await page.setViewport({ width: 1080, height: 1024 });
await browser.close();
})();
I excute node index.js, then the error came out.

I could not launch Chrome. How can I fix this error? Thanks.
Puppeteer version
19.7.0
Node version
14.21.1
Package manager
npm
Package manager version
6.14.17
Operating system
Linux
when am trying to move the image after inserting into mongo db using the function
var db = require('../config/dbconnect')
module.exports = {
//addProduct:(product,callback)=>
addProduct: (product, callback) => {
//console.log(product)
db.get().collection('product').insertOne(product).then((data) => {
console.log(data)
callback(data.ops[0]._id)
})
}
}
I am getting an error like:
{
acknowledged: true,
insertedId: new ObjectId("61054e43cffb994774d37ab0")
}

This is error first callback. Try the second argument which is the result.
db.get().collection('product').insertOne(product).then((error,data)=>
{
console.log(data)
callback(data.ops[0]._id)
})
instead of callback(data.ops[0]._id).
Try:
db.get().collection('product').insertOne(product).then((data) => {
callback(data.insertedId)
})
.catch((err)=>console.log('venk error',err))
}
My code works perfectly well with headless false, but when I change it to true I get this error :

My code :
async function getAllInfos() {
const browser = await puppeteer.launch({ headless: true });
const page = await browser.newPage();
page.setDefaultNavigationTimeout(0);
await page.goto(`https://www.japanread.cc/`, {
waitUntil: ["load", "domcontentloaded", "networkidle0", "networkidle2"],
}); //se rendre sur une page
let trs = [];
trs = tbody.querySelectorAll("tr");//the error is here
I tried to put showMo, put several things in the "waitUntil" but I get nothing, I really don't understand.
Do you know what the problem is?
This is the index.js script of the bot:
const { Client, RichEmbed } = require('discord.js')
const bot = new Client()
const util = require('minecraft-server-util')
const token = 'bot_token'
const PREFIX = 'l.'
bot.on('ready', () => {
console.log('Bot has come online.')
})
bot.on('message', message => {
let args = message.content.substring(PREFIX.length).split(' ')
switch (args[0]) {
case 'status':
util.status('IP', (PORT), (error, reponse) => {
if (error) throw error
const Embed = new RichEmbed()
.setTitle('Server Status')
.addField('Server IP', reponse.host)
.addField('Server Version', reponse.version)
.addField('Online Players', reponse.onlinePlayers)
.addField('Max Players', reponse.maxPlayers)
message.channel.send(Embed)
})
break
}
})
bot.login(token)
When I type node . in the console and I type l.status on the Discord server, it shows this error on the console:

Can anybody help? I also tried a lot of different solutions, but none of them worked.
You are using an outdatet version of discord.js. Type npm i discord.js#latest into your terminal. In the latest version of discord.js, RichEmbed() has been removed and replaced by MessageEmbed().
This is an answer based on assumption since I've never used minecraft-server-util before. Also assuming that you're using the latest minecraft-server-util,
Based on the error;
Expected 'options' to be an object or undefined, got number
And, based on this commit, You should pass the 2nd argument as an object instead of PORT since it's a type of StatusOptions instead of a number.
So, instead of;
util.status('IP', (PORT), (error, reponse) => {
You should be doing;
util.status('IP', {
port: (PORT)
}, (error, reponse) => {
i'm using nodejs to connect to mongodb and i get this error
i added the IP and nothing happend

Try this ,
const MongoClient = require("mongodb").MongoClient;
const uri ="mongodb+srv://user:userpassword#meanapp-srlw9.mongodb.net/test?retryWrites=true";
const client = new MongoClient(uri, { useNewUrlParser: true });
client.connect(err => {
const collection = client.db("test").collection("devices");
// perform actions on the collection object
console.log("connencted");
client.close();
});
For now, change your cluster setting to connect from anywhere
