room_not_found

Room not found · HTTP 404

No live room has that sid or name. Joining a room by name creates it only when the token carries roomCreate; without it, a room nobody has created is not found.

What to do: Create the room first (POST /v1/rooms), or mint the joining token with roomCreate so the first join creates it.

Where it comes from:

• Control API
• Signaling — a client's connect, a request, or an event

Branch on code; detail is for your logs and never for a user. All error codes.
