        return $this->getEntityManager($data)->getClassMetadata($this->getObjectClass($data));

The expression return $this->getEntityManager($data)->getClassMetadata($this->getObjectClass($data)) returns the type Doctrine\Persistence\Mapping\ClassMetadata which includes types incompatible with the type-hinted return Doctrine\ORM\Mapping\ClassMetadataInfo.

    {
        /** @var EntityManagerInterface|null $em */
        $em = $this->registry->getManagerForClass($this->getObjectClass($data));

The method getManagerForClass() does not exist on null.

        if (!$em) {

$em is of type Doctrine\ORM\EntityManagerInterface, thus it always evaluated to true.

            throw ORMInvalidArgumentException::invalidObject(__CLASS__ . '::' . __FUNCTION__, $data);
        }

        return $em;
