Lighthouse shows deprecated APIs (what are these?)

Basically, the Lighthouse tool integrated into Chrome DevTools and in a Firefox Extensions shows ideas/areas for improvement in front-end web development. You can view the Chrome extension here.

My problem is that whenever you run it (on a URL), it shows these deprecated APIs which when opened either:

  1. Run a google search on the link
  2. Or try to open it, but find the address is invalid

Here’s a screenshot of the problem:

You can find it under the Best Practices section. Any ideas?

Yeah same on my sites, idk what it is


Replit is setting the “Expect-CT” header to expect-ct: max-age=2592000, report-uri="" (I think it’s the same for everyone)

The sentry docs say it’s to “identify maliciously issued certificates”


Yes, exactly what @grimsteel said.
