We started getting this error when creating a Realtime WebRTC connection this week:
{"error": {"code": "invalid_offer", "message": "Invalid SDP offer. Please try again with a WHIP-compliant offer.", "param": null, "type": "invalid_request_error"}}
It seems to be upset that we start off with no media streams and only a data channel. This used to work just fine though, and we want to start off with just a data channel for text chat and only open a voice connection if the user chooses to.
Has anyone else ran into this?
