[lsnunn]

Platform

iOS

Installed

CocoaPods

Version

8.8.0 and 8.3.2

Steps to Reproduce

Not sure. Crash appears to be originating within Sentry SDK when it adds an automatic breadcrumb. We tried updating from 8.3.2 to 8.8.0 to fix it but we are still getting the issue.

Expected Result

Normal app usage

Hello @lsnunn, thanks for reaching out. Can you replicate this, or are you simply encountering it randomly in your crash reports?

[lsnunn]

We can't replicate it. In the Sentry Issue there are no in-app frames or breadcrumbs showing an action in the app. Also it is occurring in an iOS Widget. It appears to happen in the Sentry SDK right after breadcrumb tracking starts.

[brustolin]

Ok, this is for the widget then? Good to know. And only in the widget does this error occurs?

[lsnunn]

Yea only in the widget

[brustolin]

Thanks for all the information! We'll investigate this.
