Exception grouping: in_app stackframe attribute

Hello,
is Sentry considering in_app stack frame attribute? I have two almost identical exceptions that were not grouped and they differ only in a few framework frames that are in_app=false. (C#, sentry 8.18 in Docker)

EDIT: to be exact, the stack trace of one exception has a few extra frames with all having in_app=false. That’s the only difference in the stack traces.

I would very appreciate a complete and detailed grouping strategy documentation (mainly regarding stacktrace), current documentation seems to be just overview to me https://docs.sentry.io/learn/rollups/

Thanks,
Jiri

Yep. If in_app is set we only group on app frames.
