A Multiplayer API error, sent with HTTP 413. Status: the Multiplayer API is in private alpha; this code is part of its published contract.
When
The request body is larger than the route accepts.
What to do
Send less: state changes go over the socket, and each message's data is at most 4 KB.
The answer
Every error is a JSON body with a stable error code. Clients act on the codes they know and treat any other code as a failure of its HTTP status, and keep fields they do not know.
