payload_too_large

Payload too large · HTTP 413

A request body over 100 KB, metadata over 4 096 bytes of UTF-8 JSON, or a data message over the room's limit. Nothing was stored.

What to do: Keep metadata to identifiers and small facts; keep large or persistent content in your own systems and send a reference.

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.
