        $request->attributes->set(

                $routeContext[RouteContext::DESERIALIZATION_OBJECT],
                $request->getContentType()

It seems like $request->getContentType() can also be of type null; however, parameter $format of Symfony\Component\Serializer\SerializerInterface::deserialize() does only seem to accept string, maybe add an additional type check?
