/*! @brief Called when an authentication occurs, which indicates the auth session is invalid.
    @param state The @c OIDAuthState on which the error occurred.
    @param error The authorization error.
    @discussion This is a hard error (not a transient network issue) that indicates a problem with
        the authorization. You should stop using the @c OIDAuthState when such an error is
        encountered. If the \NSError_code is @c ::OIDErrorCodeOAuthInvalidGrant then
        the session may be recoverable with user interaction (i.e. re-authentication). In all cases
        you should consider the user unauthorized, and remove locally cached resources that require
        that authorization.  @c OIDAuthState will call this method automatically if it encounters
        an OAuth error (that is, an HTTP 400 response with a valid OAuth error response) during
        authorization or token refresh (such as performed automatically when using
        @c OIDAuthState.performActionWithFreshTokens:). You can signal authorization errors with
        @c OIDAuthState.updateWithAuthorizationError:.
    @see https://tools.ietf.org/html/rfc6749#section-5.2

/*! @brief Called when a network or other transient error occurs.
    @param state The @c OIDAuthState on which the error occurred.
    @param error The transient error.
    @discussion This is a soft error, typically network related. The @c OIDAuthState is likely
        still valid, and should not be discarded. Retry the request using an incremental backoff
        strategy. This is only called when using the @c OIDAuthState convenience methods such as
        @c OIDAuthState.performActionWithFreshTokens:. If you are refreshing the tokens yourself
        outside of @c OIDAuthState class, it will never be called.
