InvalidArgumentError

Thrown when an argument to a function or constructor is missing or of the wrong type — i.e. a programming or configuration error in the code that integrates this library (for example, a missing server option, or a model that does not implement a required method).

InvalidArgumentError is not an OAuth 2.0 protocol error: its invalid_argument code (HTTP 500) is not one of the error codes defined by RFC 6749 and must never be sent to an OAuth client. How it surfaces therefore depends on when it is raised:

• At construction / configuration time (missing options, a model missing a required method, or request/response not being instances of this library's Request/Response) it is thrown to your code unchanged, before any response is produced — so you can catch it while wiring up the server.
• While handling a request (for example, when a model returns malformed token data) the token and authorize handlers normalise it to a ServerError (server_error) before the response reaches the client, preserving the original error as .inner. So when you catch errors from OAuth2Server#token or OAuth2Server#authorize, expect a ServerError (inspect its .inner) for these cases — not an InvalidArgumentError.
