Protocol error (Page.createIsolatedWorld): Could not create isolated world

[Filipoliko]

Steps to reproduce

Tell us about your environment:

• Puppeteer version: 1.12.x
• Platform / OS version: Windows 7, Linux Ubuntu
• URLs (if applicable):
• Node.js version: 10

What steps will reproduce the problem?

The bug seems to be a little bit random, but it probably has something to do with links opening new tabs/windows. Here is script, which reproduces the error after some time. I was able to reproduce this error on 2 websites. The example script clicks on icon which opens a new window and then it closes the window. The error occuress when calling await browser.pages(). This error does not happen with puppeteer version <= 1.11.0.

const puppeteer = require('puppeteer');

puppeteer.launch({
	defaultViewport: {
		width: 1280,
		height: 720
	},
	headless: true
}).then(async browser => {
	let page = (await browser.pages())[0];
	await page.goto('https://www.seznam.cz/');

	for (let i = 0; i < 15; i++) {
		console.log('Round', i);
		await page.click('.timeline-article-footer__recommend-icon');
		await page.waitFor(500);
		await page.bringToFront();
		// Following line may throw an error
		let pages = await browser.pages();
		await pages[1].close();
	}

	await browser.close();
});

What is the expected result?
Everything is fine.

What happens instead?
browser.pages() throws following error:

Hopefully, this will be enough for you to reproduce the error. It seems to be related to #2671

@Filipoliko thanks for filing! I can easily reproduce with the following script:

const puppeteer = require('puppeteer');

puppeteer.launch({
  defaultViewport: {
    width: 1280,
    height: 720
  },
  headless: true
}).then(async browser => {
  let page = (await browser.pages())[0];
  await page.goto('https://www.seznam.cz/', {waitUntil: 'domcontentloaded'});

  for (let i = 0; i < 110; i++) {
    console.log('Round', i);
    const icon = await page.waitFor('.timeline-article-footer__recommend-icon');
    const [popup] = await Promise.all([
      new Promise(x => page.once('popup', x)),
      icon.click(),
    ]);
    await popup.close();
  }
  await browser.close();
});

This turns out to be a dupe of #4011; it's already fixed upstream in chromium and will be fixed in the next release.

Glad to hear that, thank you and sorry for the duplicit issue.
