Chat error codes

When a chat operation fails, the service returns an error with a code. This page lists the codes by area.

In the client SDK, the code is on ChatError.code (the SDK also defines a few client-side codes; see the Chat client SDK on GitHub). In the REST API, it's the code in the error response. The service can add codes in newer versions, so handle unknown codes too.
