Steps to Reproduce

Not able to reproduce myself.

Expected Result

Reported error should've some more information on which fetch requests are failing.

Actual Result

Following error has been flooding our sentry dashboard since last 2 days. Thousands of such reports have been coming in. The error indicates that a fetch request is failing but doesn't really give any more info into which fetch requests are failing and why. Also, the stacktrace is pointing to some Sentry error reporting apis which has me confused as to whats actually going on here.

is there a possibility to upgrade your sdk version? we've done some minor changes to stacktrace fetching so it might help

but for some context: sometimes unhandled errors simply do not have stacktraces attached so we do our best by calling StackTrace.current but in some cases for example async it won't capture the whole context which I suspect has happened here.

@buenaflor Thanx for the info! We're shipping a new build with latest sentry version 8.8.0. Will let u know if it helps in anyway.
