I am using the latest Version of Ionic Storage for Angular, Capacitor Preferences and Firebase. I don't really know if some of these Libraries are the cause of this error.

I hope someone of has some more information about this error.

Kind reagards, Marius

This looks like an Apple bug, there have been similar issues in the past, it was supposedly fixed on iOS 13, so since Capacitor only supports iOS 13+ it's probably a regression. Report it on https://bugs.webkit.org/

This is the old issue and people is commenting on it, but I think it would be better to create a new one https://bugs.webkit.org/show_bug.cgi?id=197050

Thank you for the fast resonse @jcesarmobile! What I find strange is that my app supports iOS 15+ and I see errors in Sentry for iOS 17+. Can you say anything more about that?

[jcesarmobile]

As I said, check the link, there are recent comments about being broken on iOS 17.4

My users are also being affected by this issue starting with iOS 17.4.

FYI, I posted a new bug on bugs.webkit.org: https://bugs.webkit.org/show_bug.cgi?id=273827
