[Technical Questions] Firebase Firestore WatchStream Error: “Unknown Internal Error

[jennleww]

In what area do you have a technical challenge?

Xcode, Simulator & Previews

Description

I am experiencing an issue with Firebase Firestore in my app after running the firebase emulators:start command in my terminal. The Firestore WatchStream fails with an internal error, causing the app to operate in offline mode. The logs show the following error messages:

Reproduction

1. Launch the app and try to access Firestore data.
2. The app fails to connect to Firestore and logs the errors mentioned above.
3. The issue occurs inconsistently but is frequent when the app starts.

Expected behavior

The app should be able to establish a connection to Firestore and fetch data without failing into offline mode when a stable internet connection is available.

Additional context

Firebase SDK version: 11.3.0

Hi @jennleww! Are you launching the app in the simulator? Is this on main? It looks like the app is attempting to access the Cloud Firebase (not the emulator). What launch arguments are you using (e.g. is the feature flag for using the emulator enabled)?

[jennleww]

Yes, in simulator on a different branch. How do I check which launch arguments I'm using?
