API Platform version(s) affected: 4.2.2 (after having updated from 4.1.23)

Description

The JSON LD schema of a resource's simple output DTO seems to now consider an array of strings as null[] where it was string[] on APIP 4.1.23

How to reproduce

We use openapi-typescript to transform API Platform's documentation to types:

npx openapi-typescript "https://${SERVER_NAME}/docs.jsonopenapi" -o ./pwa/types/api-schema.d.ts

Possible Solution

Additional Context

The introduction of the HydraItemsBase of #7426 through #7444 is great. Could it have affected anything else?

DTO Shape:

<?php
namespace App\Domain\Shared\Specification;
use Symfony\Component\Serializer\Attribute\Groups;
#[Groups('me:read')]
final readonly class SpecificationResult
{
 private function __construct(
 public bool $passed,
 /**
 * @var list<non-empty-string>
 */
 public array $messages = [],
 ) {
 }
}
