Thanks for reaching out, Rhythm. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
The errors "failed to send transcription, room closed: channel closed" and "engine: connection error: engine is closed" occur when operations are attempted on a LiveKit room or engine that has already been closed. This typically happens due to: • Room disconnection events (e.g., room deleted, all participants left, network issues) • Session closure (user ends conversation, session is closed, or unrecoverable error) • Connection failures (network interruptions causing websocket disconnects) Resolution strategies: • Before performing operations, always check that the engine and transports are still connected and not closed. • Implement reconnection logic: ensure your agent waits for successful reconnection before resuming operations. The engine supports automatic reconnection with configurable retry attempts. • Handle errors gracefully: distinguish between expected closures (such as intentional session end) and unexpected failures that should trigger reconnection attempts. • Monitor connection events and clean up resources when sessions end to avoid operations on closed connections. Review your agent's connection state management and error handling to ensure operations are only attempted on active sessions and connections. If you need code-level examples or further troubleshooting, please specify your agent version and any custom connection handling logic in use.
