Solutions

1. Confirm the request code sent to the broker is supported by the StatefulAuthenticationStrategy; only supported request types can be authenticated through this path.
2. Upgrade the client/broker to matching versions so the request type is recognized.
3. If this is a custom or new request type, implement or register an appropriate AuthenticationStrategy for it.

When it happens

Trigger: Occurs when the stateful authentication strategy receives a request type it does not support.

Common situations: Client sends a request code not handled by the stateful authentication strategy, e.g. an admin or unsupported operation routed to authentication.
