Do you do anything with LiveKit Agents?

Do you do anything with LiveKit Agents?

@davidliu We do have agent(s) in the LiveKit server side. One of them is for transcribing user's audio in to text (speech-to-text) by connecting to Deepgram. We don't have any kind of LiveKit Agents in client side.

@davidliu Do you need any further info from us?

Hmm, is it possible you've set the lk.agent.state attribute manually to an invalid state?

@davidliu No, we don't set this manually anywhere.

Hmm, in any case, I've changed it to not throw on invalid data here. Fixed in #847.
