How to validate the UUID parameter before SQL request for a "GET item" request in API-Platform?

Using:

• PostgreSQL 11 with uuid_generate_v4 type
• Symfony 4.4.11
• Api Platform 2.5.6

I have an Entity with the following Id :

/** * @ORM\Entity(repositoryClass="App\Repository\ContractRepository") * @ORM\HasLifecycleCallbacks */class Contract{    /**     * @ORM\Id()     * @ORM\GeneratedValue(strategy="UUID")     * @ORM\Column(name="id", type="guid", unique=true)     */    private $id;[...]

I generate the following route with Api Platform :

App\Entity\Contract:  itemOperations:    get:

So I get a generated route like /contracts/{id}

Currently, if I do /contracts/TEST, it will try to do the SQL request with "TEST" in a where clause and so will fail as a 500.

I would like to prevent this behaviour by asserting that the {id} parameter is a UUID_v4 and return a 400 if not.
