page-experience: invalid url issue

Hi,

Is there any issue regarding https://amp.dev/page-experience/ ,

**here's an example of a valid amp page but detected as invalid url in page-experience**

https://www.freecodecamp.org/news/pwa-vs-amp-what-is-the-difference-and-how-do-you-choose/amp/

**here's some error in browser console**

Thanks

Reproduce the report at https://amp.dev/page-experience/ using the linked freecodecamp AMP URL, and inspect the browser-console errors shown in the issue. Trace the page-experience URL-validation entry point and add a regression case for this URL; done means the valid AMP page is no longer reported as invalid.
