Error when agent disconnects

[egoldschmidt]

When the agent disconnects after finishing its audio, I see this error (I don't believe it causes any issues but I'm not quite sure).

FWIW here's how I disconnect (advice welcome if this is not the right way to do this):

        await voice_assistant.aclose()
        await ctx.room.disconnect()

Error:

Hey, this is indeed harmless. I will take a look at ignoring these errors when the room is closed
