As I've reported a few months ago, there's still an incompatibility or slight issue together with the PWA extension, causing thousands of PHP NOTICEs in days being reported to Sentry and logged on disk.
PWA is using and recache triggering notices on following paths:
- /sw
- /webmanifest
- /offline
Edit: Apologies, (for some reasons( I completely forgot to add the actual PHP NOTICE for your convenience:
ErrorException: Undefined offset: 0
#43 /vendor/reflar/recache/src/Replacers/Data.php(66): FoF\Sentry\SentryServiceProvider::handleError
#42 /vendor/reflar/recache/src/Replacers/Data.php(66): Reflar\ReCache\Replacers\Data::replaceInCachedResponse
