Error with latest version of puppeteer

[jibon57]

Hello,

Thanks for your library. I am using it with puppeteer like this:

const puppeteer = require('puppeteer');
const Xvfb      = require('xvfb');

var xvfb        = new Xvfb({silent: true});
var options     = {
  headless: false,
  args: [
    '--disable-infobars',
    '--no-sandbox',    
    '--shm-size=1gb',
    '--disable-dev-shm-usage',
  ],
}


async function main(){
  xvfb.startSync()
  const browser = await puppeteer.launch(options);
  const page = await browser.newPage();
  await page.goto('https://news.ycombinator.com', {waitUntil: 'networkidle2'});

  await browser.close();
  xvfb.stopSync()
}

main()

But I am getting errors like this:

(node:25099) UnhandledPromiseRejectionWarning: Error: Navigation failed because browser has disconnected!

Any suggestion please?

Can't reproduce with node 13.11.0, xvfb 0.3.0, puppeteer 2.1.1, Chromium 80 on Linux.

[jibon57]

Thanks for your quick response my node version v8.17.0.

  "dependencies": {
    "puppeteer": "^2.1.1",
    "ws": "^7.2.3",
    "xvfb": "^0.3.0"
  }

I am testing from Ubuntu 16.04 LTS

Are you able to successfully run other GUI programs instead of Chromium through Puppeteer?

If yes, then it's likely not an issue with xvfb.

Why are you using headless: false,? With headless: true, you can run Chromium without a display. Certain features such as extensions won't be available, but if you don't need it you may as well run in headless mode.

Thanks for reply @Rob--W . Actually I am using screen sharing feature of Chromium to live record. It's working with older version of Puppeteer but new version having that problem. If I don't use xvfb then it's working fine

@Rob--W if I try like this way in terminal then it's working:

xvfb-run -a --server-args="-screen 0 1280x800x24 -ac -nolisten tcp -dpi 96 +extension RANDR" node test.js

How can I do that using your module? I tried like this:

var xvfb        = new Xvfb({
    silent: true,
    xvfb_args: "-screen 0 1280x800x24 -ac -nolisten tcp -dpi 96 +extension RANDR"
});

But not working. Sorry, I ain't expert on this.

[Rob--W]

xvfb_args should be an array of individual arguments.

Try

var xvfb        = new Xvfb({
    silent: true,
    xvfb_args: ["-screen", "0", "1280x800x24", "-ac", "-nolisten", "tcp", "-dpi", "96", "+extension", "RANDR"],
});

@Rob--W thank you so much!! It's working now 💯
