Since Symfony 7.3, arrays of IRIs in inputs are not converted to their respective objects when defined in a promoted constructor

[simondaigre]

API Platform version(s) affected: 4.1.15

Description
In my project, I only use DTOs. Before Symfony 7.3, with the following example, I retrieved the object with the property $users filled with UserDTOs in my processor. Since Symfony 7.3, and without any other changes on my part, I only retrieve an array of IRIs.

phpdocumentor/reflection-docblock is still installed.

Let me know if you want a reproducer.

How to reproduce

DTO :

#[ApiResource(
    shortName: 'Location',
    operations: [
        new Post(
            uriTemplate: '/locations',
        ),
    ],
    openapi: new Operation(
        tags: ['Location']
    ),
    processor: LocationProcessor::class,
    stateOptions: new Options(entityClass: Location::class),
)]
readonly class LocationInputDto
{
    public function __construct(
        #[Assert\NotBlank]
        public ?string $name = null,
        /** @var UserDto[] */
        public ?array $users = [],
    ) {
    }
}

Example request payload :

{
    "name": "Tour Eiffel",
    "users": [
        "/api/users/1",
        "/api/users/2"
    ]
}

We should have tests for these kind of use cases would you be able to provide a reproducer?

Sure, here it is : https://github.com/simondaigre/apip-repro

OK, I found the culprit, changing this new setting to false solve the problem :

framework:
    property_info:
        with_constructor_extractor: false

Which is weird, shouldn't be the opposite ?

I had a similar issue after migrating to Symfony 7.3 and setting framework.property_info.with_constructor_extractor=true.

In order to fix this, I had to move the type declaration to the constructor params:

+  /**
+   * @param UserDto[] $users
+   */
    public function __construct(
        #[Assert\NotBlank]
        public ?string $name = null,
-       /** @var UserDto[] */
        public ?array $users = [],
    ) {
    }

I'm not sure if this should be considered a bug or expected behavior.

We must not have that use case let me pin the issue.

An issue has been opened on the Symfony repository on this subject.
