Symfony - Could not convert database value to uuid

Question

In my Symfony project I am using \Ramsey\Uuid\Uuid library for persisting user object with unique uuid.

$user->setUUid(Uuid::uuid4());

No I want to search for an user object by that uuid like:

$uuid = $this->userRepo->findOneBy(['uuid' => $uuid]);

And I am passing it trough my request like:

http://localhost:8080/api/user/039ade1a-c111-419c-9904-67b62162208

but I get:

"Could not convert database value "039ade1a-c111-419c-9..." to Doctrine Type uuid"

Should I somehow convert it again to uuid?

I tried:

    return $this->createQueryBuilder('p')
        ->where('p.uuid = :uuid')
        ->setParameters(
            'uuid' => Uuid::fromString($uuid)->getBytes()
        )
        ->getQuery()
        ->getOneOrNullResult();

Error still the same.
