Validation does work in my current GraphQL implementation.

As proposed in the docs I added a validation rule to the first arg of the first field of my root mutation. I also added validation "cascade" to the second arg that is an input object.

See the following example:

RootMutation:
    type: "object"
    config:
        description: RootMutation type
        fieldsDefaultAccess: "@=hasRole('ROLE_USER')"
            updateUser:
                description: Updates a user
                type: "User!"
                access: "@=hasRole('ROLE_USER') && isGranted('user_access', args['id'])"
                args:
                    id:
                        description: ID of the user
                        type: "ID!"
                        validation:
                            - Email: []
                    user:
                        description: Data of the user to update
                        type: "UpdateUser!"
                        validation: cascade

UpdateUser:
    type: "input-object"
    config:
        description: Input object to update a user
        fields:
            displayName:
                description: Display name of the user
                type: "String!"
                validation:
                    - Length:
                          min: 5
                          max: 10

I can see the validation rules are basically processed. When I add a constraint that does not exist, it says:

In TypeBuilder.php line 632:
                                                                               
  Constraint class 'Symfony\Component\Validator\Constraints\WrongEmail' doesn't exist.

I can also see the constraints are added to the auto generated type classes in app/var/cache/test/overblog/graphql-bundle/__definitions__:

final class RootMutationType extends ObjectType implements GeneratedTypeInterface, AliasedInterface
{
    public const NAME = 'RootMutation';
    
    public function __construct(ConfigProcessor $configProcessor, GraphQLServices $services)
    {
        $config = [
            'name' => self::NAME,
            'description' => 'RootMutation type',
            'fields' => fn() => [
                'updateUser' => [
                    'type' => fn() => Type::nonNull($services->getType('User')),
                    'description' => 'Updates a user',
                    'args' => [
                        [
                            'name' => 'id',
                            'type' => Type::nonNull(Type::id()),
                            'description' => 'ID of the user',
                            'validation' => fn() => [
                                new SymfonyConstraints\Email([]),
                            ],
                        ],
...

However, I cannot see the Email validator actually being called. I can put in any value as the user ID. And I cannot see the Length constraint being checked for display name either. Any string value is accepted.

The only thing I get is a deprecation notice:

Remaining indirect deprecation notices (2)

  2x: Creation of dynamic property GraphQL\Type\Definition\InputObjectField::$validation is deprecated
    2x in MutationServiceTest::testUpdatingUser from App\Tests

I tried to debug the the validation process and set break points in different places like in Overblog\GraphQLBundle\Validator\InputValidator, but those lines are never crossed.

---

Did I miss anything in the docs? Does the validation have to be activated somehow?

Can somebody please confirm this is a bug? Or tell me a good place where to set a debugger breakpoint so I can investigate why validation takes not place in my project?

Thank you!
