TypeError: Failed to construct 'URL': Invalid URL

This is for the chrome extension “axe - Web Accessibility Testing” which I believe is also developed by dequelabs. I was unsure where else to post this error.

Expectation: Not console error

Actual:

Uncaught (in promise) TypeError: Failed to construct 'URL': Invalid URL
    at y (content.bundle.js:33)

Motivation: So I can read more important console errors relating to development

axe - Web Accessibility Testing version: 4.8.4

Browser and Assistive Technology versions
Browser: Chrome 88.0.4324.190 (Official Build) (64-bit)
Operating System: Windows 10

This occurs on any page, even Google. The error usually occurs

multiple times.

Thanks.

Close, but not quite!

We were trying to construct an instance of a URL for communicating with the axe API server (https://axe.deque.com) before the server’s URL is set. We keep the server’s URL in the extension’s storage. The code looked something like this:

var stored_url = await get_from_browser_storage('axe_server_url')
var url = new URL(stored_url)

The fix resembles:

var stored_url = await get_from_browser_storage('axe_server_url')
var url = new URL(stored_url || DEFAULT_SERVER_URL)
