It seems like $context defined by $this->convertContext($context, self::SERIALIZATION) on line 48 can also be of type object<JMS\Serializer\DeserializationContext>; however, JMS\Serializer\SerializerInterface::serialize() does only seem to accept null|object<JMS\Serializer\SerializationContext>, maybe add an additional type check?
