When switching message/event streams, the old stream's 'end' or 'error'
events could fire after the new stream was created. Since activeMessageSubscription
was already updated to the new session, the old stream's events would
incorrectly trigger reconnection, causing TSS message routing to fail.
Fix:
- Remove event listeners from old stream before canceling
- Use closure to capture current stream reference
- Check if event is from current active stream before triggering reconnect
This fixes the "Not connected" error during co-sign TSS message routing.
