Fix StacklessClosedChannelException

✅ Solution

The "StacklessClosedChannelException" in firebase-sdk often arises from premature closing of gRPC channels used for communication, especially during emulator interactions or during stream handling. Ensure proper error handling within your code to avoid closing channels before operations are complete and consider implementing retry mechanisms with exponential backoff for transient network issues. Review your emulator setup to ensure proper resource allocation and avoid overwhelming the system with concurrent tasks.
