DevTools Lighthouse: Best Practices displays "..." as a Deprecation/Warning

I'm testing the performance of my website with Lighthouse DevTool but I can't score 100% in Best Practices because keeps showing this as a problem: Lighthouse Deprecation/Warning

Does anybody know what this means? How could I solve it?

You can find the specific errors in the "Issues" tab where the "Console" output is.

Also getting this, so you're not alone. Wondering if it was a recent Chrome bug I tried here - https://www.webpagetest.org/ and got the same useless error.

After a bit more digging, I found this closed issue on the lighthouse github repo.

https://github.com/GoogleChrome/lighthouse/issues/14233

So, it's been fixed, but only in version 10. Chrome 105 seems to be using lighthouse 9.6.2 and npm at the present time seems to install 9.6.7 (which has the same bug).

You can run the latest version by pulling the repo from github, building and running on the command line. See instructions here

https://github.com/GoogleChrome/lighthouse#develop

Note, the build doesn't work on an M1 mac, due to i386 specific build tools. I had to dig out my old macbook to get this working.
