App Crash from Firebase Remote Config #12550

Closed nik6018 closed 7 months ago

nik6018 commented 7 months ago

Description

The app is crashing immediately after opening, as indicated from Crashlytics as it's tagged under "Early crashes". The crash is happening randomly.

When the app starts up I have made sure that func fetch( withExpirationDuration expirationDuration: , completionHandler: ((RemoteConfigFetchStatus, ?) -> [Void])? = nil ) method is only invoked once to avoid any multiple calls

I am also using RemoteConfigRealTimeUpdate as well to fetch latest values whenever changes happen.

Can anyone provide me guidance on how I can resolve this crash as it's pointing to RCNConfigRealtime.m:449 and I have no insight on what's causing it

Hi @nik6018, could you share a sample app that reproduces the issue? Thanks.

nik6018 commented 7 months ago

Hi @rizafran I am unable to reproduce this issue every time and it's occurring in very rare occasions

rizafran commented 7 months ago

@nik6018, could you share your full stack trace of the issue? Based on the stack trace you provided, it looks like there are missing UUIDs and the crashes aren't symbolicated.
