This is partially #44 since you can't do the channel lookup in DMs anyway. (see #44 for why) You did disambiguate but the prompting just isn't there to support that. You have to make that kind of query in the channel itself. But that shouldn't give you that error. It looks like the LLM came back with a bad function call. (it's hallucinating a function prefixed with a team name) We should handle this case better.
