During an ongoing agent session in a room ( I am using explicit dispatch ). If a user disconnects, then the agent is still there in the room for some time. So, if the user rejoins again, i am not dispatching the agent again as I am able to see that one agent is already there but that agent isn't responding to the user. I can see the following logs as soon as user leaves- 2025-08-20 133255,250 - DEBUG livekit.agents - session closed {"reason": "participant_disconnected", "error": null, "pid": 848, "job_id": "AJ_nXeSguRScspv"} 2025-08-20 133339,805 - INFO root - ignoring text stream with topic 'lk.chat', no callback attached {"pid": 848, "job_id": "AJ_nXeSguRScspv"} And when the user joins again, I see the following logs when user tries to interact - 2025-08-20 133339,805 - INFO root - ignoring text stream with topic 'lk.chat', no callback attached {"pid": 848, "job_id": "AJ_nXeSguRScspv"} Explain why is agent not responding in the case of user - reconnect. My understanding is that the agent should either leave the room Or if it is still there, it should be responding!

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

1. i am currently listening to the webhook events. I listen to the evnet of when a user joins a room. And if there is no agent in that room already I dispatch the agent otherwise I do nothing. 2. I am handling it manually through api 3. Name is setup correctly I am sure of that, otherwise agent wouldn't have joined at all

To help figure out why the agent stops responding after a user reconnects, could you share a bit more info with me? • How does your agent handle

participant_connected

and

participant_disconnected

events? • Which webhook events are you currently working with? • Have you noticed any error messages or logs when the agent stops responding?

1. In the agent worker side I am not doing anything about

participant_connected, participant_disconnected

events, I only listen to webhook events on another server which handles agent dispatch. 2. Its called - participant_joined event I also check the type of participant that has joined 3. Not particularly, no!

Hey there! It looks like the issue might be tied to how your webhook handles the reconnection process. No worries though—here are a few friendly tips to help make sure your agent responds smoothly after a user reconnects: • Webhook Event Handling: Double-check that your webhook can tell the difference between when a participant joins for the first time and when they’re reconnecting. The

participant_joined

event can pop up during reconnections, so your logic should make sure the agent’s state is updated or re-dispatched if needed. • Agent Re-dispatch: It might be helpful to add some logic that explicitly re-dispatches the agent whenever a user reconnects. You can do this using the

AgentDispatchClient

or similar API calls. • Connection State Monitoring: Keep an eye on the agent’s connection status to make sure it stays active and ready after a reconnection. If the agent gets interrupted during this process, it might need to be re-initialized. • Metadata Usage: Try using metadata in your dispatch logic to keep track of and manage how the agent behaves dynamically. This can be a great way to tailor responses based on reconnection situations. If you want a hand implementing these tweaks or need help debugging any part of your webhook logic, just give me a shout—I’m here to help!
