Puppeteer blocked at .newPage()

I want to use Puppeteer to generate PDF.

My environnement dev

  • WSL2 Debian Buster
  • Node v12.18.1
  • npm 7.5.4
  • Puppeteer 8.0.0

I tried many tutorials on the web to do it. But the code is blocked on browser.newPage()

const browser = await puppeteer.launch();
console.log(await browser.version()); //HeadlessChrome/90.0.4427.0 
const page = await browser.newPage(); //after it does nothing

Here the debug (six last lines) :

  puppeteer:protocol:RECV ◀ {"id":4,"result":{"sessionId":"B3D2567E07203D4A096A495710466966"}} +0ms

Thanks,

Solution

  • I have fixed the issue of my case:

    Use dumpio: true to display log of Puppeteer. After that, I found the error with libX11-xcb.so.1 and disabled the gpu.

      browser = await chromium.launch({
      args: ["--disable-gpu"]
    });
