[BUG] Malformed URL leads to UnhandledPromiseRejection

[roikoren755]

Context:

• Playwright Version: 1.7.1
• Operating System: both on Mac running locally, and when ran via a Google CloudFunction on a linux based docker
• Node.js version: 13.14.0 locally, 12.20.0 on Google CloudFunction
• Browser: chromium
• Extra: We couldn't get the CloudFunction to run with just Playwright, but installing Chromium via Puppeteer and using that executable worked 😆 . Locally I am using just Playwright.

Code Snippet

Help us help you! Put down a short code snippet that illustrates your bug and
that we can run and debug locally. For example:

const {chromium, webkit, firefox} = require('playwright');

(async () => {
  const browser = await chromium.launch();
  const page = await browser.newPage({ ignoreHTTPSErrors: true });
  await page.goto('https://www.youtube Panel Title.com/'); // Notice the spaces in the URL
})();

Describe the bug
When passing a malformed URL to the page.goto method, an UnhandledPromiseRejection is thrown, even if I wrap my code in a try-catch block. I got around this issue by trying to create a URL object from the string I get before trying to open it:

try {
  new URL(url);
} catch (e) {
  console.warn('Malformed URL', url);
  return;
}

The same error occurs occasionally, when the page I load has a well formed URL, but one of the assets it tries to load doesn't. This crashes the running function, even though all of my code is wrapped in a try-catch block, or uses await-to-js to catch rejected promises.

Add any other details about the problem here.

This is the error log I get when trying to open a malformed URL.
