Thanks for reaching out, Pavan. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

can you please solve my issue

It looks like your LiveKit agent worker ran into a

TimeoutError

and

CancelledError

, which usually pop up because of task coordination hiccups, network issues, or resource management challenges. Here are a few friendly tips to help you troubleshoot: • Check Network Connectivity: Make sure there’s a steady connection between your worker and the LiveKit server. • Monitor Server Load: Take a peek to see if the server isn’t overwhelmed and can smoothly handle job dispatching. • Adjust Timeout Settings: Try increasing timeout values for operations that might need a bit more time. • Handle Task Cancellation: Double-check that your cleanup code and worker shutdown properly manage

CancelledError

. • Enable Detailed Logging: Add some logging around those timeout-prone spots to help pinpoint what’s going on.
