Why assign $authorization to itself?

            if (false !== strpos($authorization->getQueryParam('response_type'), 'id_token') && !$authorization->hasQueryParam('nonce')) {
                throw new \InvalidArgumentException('The parameter "nonce" is mandatory when the response type "id_token" is used.');
            }

            return $authorization;
        } catch (\InvalidArgumentException $e) {
            throw new OAuth2AuthorizationException(400, OAuth2Exception::ERROR_INVALID_REQUEST, $e->getMessage(), $authorization, $e);
        }
    }
