Lighthouse in DevTools errors/hangs on installability checks

Latest:

We have a fix that should land in Canary ~soon: chromium-review.googlesource.com/c/chromium/src/+/3318838

We’ll request a merge to Chrome 97 (scheduled to release Jan 4).

In the meantime, you can avoid the hanging by disabling Clear Storage

Before 98.0.4711.0, some sites with service workers would hang indefinitely while determining if there were any installability errors. With 98.0.4711.0, hanging should occur less often (these issues were fixed), a report will be generated and this error will be seen in the installable audit: Lighthouse could not determine if there was a service worker. Please try with a newer version of Chrome.. This message is aspirational, as there is not yet a fix for the underlying cause.

However, there are still URLs that will hang indefinitely:

• https://www.enricofromrome.eu/edb6/
• https://restaurantguru.com/
• https://club.triboon.net/

Debugging shows that the target for the service worker is never resumed.

Some URLs that will show the new could not determine message (and not hang):

• https://wheresthebus.com/
• https://naughty-yonath-344d6c.netlify.app/
• https://periodex.co/
• https://m.warsztat24.pl/
• https://www.oklahomadriver.com/

The fix has reached stable.

Confirmed with latest Canary 98.0.4755.0 that all the URLs in the original post work, and none return the temporary error message.

Will keep this open to track the merge into Chrome 97 and (maybe) 96.
