The LiveKit dispatch API doesn’t currently have a built-in feature to return an error if an agent isn’t found right when you create a dispatch. This is because the dispatch process works asynchronously and doesn’t check agent availability during creation. But don’t worry! You can handle this on your side by keeping an eye on participants and using timeouts. For instance, once you connect to a room, you can watch

room.remoteParticipants

to see if the agent you’re expecting joins, and set a timeout to catch if they don’t show up. I’d be happy to help you set up a pre-dispatch check for agent availability or guide you through creating a timeout and retry approach in the SDK you’re using. Just let me know what would be most helpful for you!
