This method seems to be duplicated in your project.

    {

            $response = $event->getResponse();
            foreach ($responseContext->getHeaders() as $key => $value) {
                $response->headers->set($key, $value);
            }

            $event->setResponse($response);

It seems like $response defined by $event->getResponse() on line 89 can be null; however, Symfony\Component\HttpKernel\Event\GetResponseEvent::setResponse() does not accept null, maybe add an additional type check?

        }

This method seems to be duplicated in your project.

It seems like $response defined by $event->getResponse() on line 105 can be null; however, Symfony\Component\HttpKernel\Event\GetResponseEvent::setResponse() does not accept null, maybe add an additional type check?
