Indicates a bad request error. It could be caused by an unexpected request body format or other forms of request validation failure, such as invalid json. Usually serves application/json content, although in some cases simple text/plain content might be returned by the server's middleware.

Unauthorized. The REST Catalog SHOULD respond with the 401 UnauthorizedResponse when the access token provided is expired, revoked, malformed, or invalid for other reasons. The client MAY request a new access token and retry the request.

Forbidden. Authenticated user does not have the necessary permissions.

Not Found - NoSuchTableException, Table to drop does not exist

This is an optional status response type that the REST Catalog can issue when the token has expired. The client MAY request a new access token and retry the request. 401 UnauthorizedResponse SHOULD be preferred over this response type on token expiry.

The service is not ready to handle the request, request could have been partially processed.
The service may additionally send a Retry-After header to indicate when to retry, a non idempotent request should only be retried by the client when the Retry-After header is present.

A server-side problem that might not be addressable from the client side. Used for server 5xx errors without more specific documentation in individual routes.
