Agent dispatch silently fails and doesn't join room

Telephony

Environment:

  • LiveKit Cloud (call-claio project)
  • Agent: medical-assistant-staging (CA_FsdqYZFAQkRo)
  • Deploy version: v20260409143835

Issue:
Agent dispatches intermittently fail with no error surfaced. The agent shows as RUNNING in the dashboard, but when a dispatch is created via create_dispatch(), the agent never joins the room.

Evidence:

  • Session RM_qWqC2XBG6uj3 (Apr 9, 11:31 AM ET)
  • Room was created at 11:31:53, deleted at 11:32:25
  • 0 participants joined — no agent, no SIP
  • Events show only API.CreateRoom → Room ended → API.DeleteRoom
  • Agent insights tab shows nothing
  • No dispatch event visible in session events
  • A follow-up test call minutes later succeeded

Looks like you deployed a new agent version before that, and something was wrong with that agent code. To debug, you need to look in your agent logs to see what the issue was, since I do not have access to them. The new agent was not available for about 51 minutes so there was no work to service the job.

Looks like something similar happened with RM_hAGGRHFSC66b
