puppeteer: Timed out after 30000 ms while waiting for the WS endpoint URL to appear in stdout!

Adding timeout while launching the puppeteer will solve this issue. Try adding timeout:0 in launch options.

is anyone can find solution ?

Same issue, however, I will note that adding timeout: 0 as @rohinthr suggested, seems to solve it so far, however, I still need to do more testing to confirm.

On puppeteer v 21.1.1. Using google cloud function gen2 onObjectFinalized trigger with 16GiB memory, 4 cpu, and 120 second timeout.

On first, and intermittently on subsequent runs of this Cloud Storage trigger function, I am getting TimeoutError: Timed out after 30000 ms while waiting for the WS endpoint URL to appear in stdout!. So, this is still very much an issue and unless someone can point out in my code something I’m missing, I am waiting for the browser to close before the function completes, etc.

In package.json I had to add:

"scripts": {
  "gcp-build": "node node_modules/puppeteer/install.js"
}

And then at root of project I added the .puppeteerrc.cjs config file:

const {join} = require('path');

/**
 * @type {import("puppeteer").Configuration}
 */
module.exports = {
    // Changes the cache location for Puppeteer.
    cacheDirectory: join(__dirname, '.cache', 'puppeteer'),
};

Puppeteer code:

const browser = await puppeteer.launch({
    headless: 'new',
    timeout: 0,
})

const page = await browser.newPage()

// Load the html file that triggered onObjectFinalized as string and pass to setContent
// So, in my use case I'm not even loading a website with puppeteer, just passing html.

await page.setContent(html, { waitUntil: 'domcontentloaded' })
await page.emulateMediaType('screen')

const PDF = await page.pdf({
    path: `/tmp/${pdfFilename}`,
    margin: { top: '.5in', right: '.5in', bottom: '.5in', left: '.5in' },
    printBackground: true,
    format: 'A4',
})

await browser.close()
