Python agents: handling exceptions in your entrypoint

Unhandled exceptions in a LiveKit agent’s entrypoint function cause the agent to leave the room but do not automatically terminate an established SIP call, potentially leaving callers connected to a silent room. This behavior is intentional because the framework cannot assume that an agent failure should end a shared room, disrupt other participants, or prevent another recovery strategy. To avoid this outcome, developers should wrap entrypoint setup in try/except, log the original failure, and select cleanup suited to the application: delete the room to disconnect everyone, remove only SIP participants to preserve other attendees, or briefly notify the caller before hanging up. Errors occurring after an AgentSession starts should instead be handled through the session error event, while fallback adapters can improve resilience by switching among STT, LLM, or TTS providers. Recommended practices include closing API clients in finally blocks, handling cleanup failures separately, and considering shutdown callbacks for cleanup that must run regardless of how the entrypoint exits.
