When i set that value to true or just don't write it , it works, but i am still wondering what is the reason and how can i fix it ? to show the browser
i have already tried adding these flags but it didn't work either
const browser = await puppeteer.launch({headless: false,args: ['--no-sandbox', '--disable-setuid-sandbox']});

const twitterClient = new TwitterApi(tokens.BEARER);
const roClient = twitterClient.readOnly;
const user = await roClient.v2.userByUsername('plhery');
console.log(user);

i'm only trying to launch the exemple of the app kit OrbitDB which is :
import OrbitDB from "orbit-db";
import IPFS from "ipfs";
async function main () {
// Create IPFS instance
const ipfsOptions = { repo : './ipfs', }
const ipfs = await IPFS.create(ipfsOptions)
// Create OrbitDB instance
const orbitdb = await OrbitDB.createInstance(ipfs)
// Create database instance
const db = await orbitdb.keyvalue('ipfs_db')
}
main()
you can find it here : https://github.com/dappkit/aviondb#using-nodejs
but the problem is when i launch it, i got these errors :

i seriously don't know what to do, i tried to clear the cache, to delete node_modules and package-lock.json, and do a npm install, but nothing changed, i got the same error, do you have any idea to fix this ?
This error clearly points to an incompatibility between IPFS and OrbitDB.
The latest version of js-ipfs that OrbitDB v0.26.1 supports is 0.55.4.
You should change the ipfs (or ipfs-core) version in your package.json to ^0.55.4.
Note: The upcoming OrbitDB v0.27, will support the latest IPFS version.

This is the code of the module (btw dont mind but th "ok" its for testing.
const router = require("express").Router();
const User = require("../models/User")
//REGISTER
router.get("/register", async (req,res)=>{
const user = await new User({
username:"john",
email:"john#gmail.com",
password:"123456"
})
await user.save();
res.send("ok");
});
module.exports = router
the syntax is right, needed to format it for containing on the "code" on the question.
Thanks in advance, Francesco
You are trying to call the model without even establishing a connection with the database. You need to use async/await with connect() or createConnection().
When try to run this url page this is the error i keep getting. Please Advice.

const puppeteer = require('puppeteer');

I have some simple code
const puppeteer = require('puppeteer');
async function getPic() {
const browser = await puppeteer.launch({headless: false});
const page = await browser.newPage();
await page.goto('https://www.paniniamerica.net');
await page.screenshot({path: 'panini.png'});
await browser.close();
}

I noticed that this specific website just times out. Other websites like google.com or even stackoverflow.com work fine. Is this website blocking this type of behavior?
This is the error it spits out.
