Skolem IRI @id for Entity which uses a DTO to change the output response

[jenbhu]

I'm using the API platform v3.1.14

I'm using a DTO to return a custom output for an entity. However it is generating a skolem iri instead of the Entity of the id for the @id attribute

I've tried the suggestions in api-platform/core#5451 but it is not working.

<?php

namespace App\Entity;

use ApiPlatform\Metadata\ApiResource;
use ApiPlatform\Metadata\Get;
use Doctrine\ORM\Mapping as ORM;
use App\Repository\KeyRepository;
use App\Dto\KeyOutput;
use App\State\KeyOutputProvider;
use ApiPlatform\Metadata\Post;

#[ApiResource(
    shortName: 'Key_new',
        operations: [
                new Post(),
        ],
)]
#[Get(
    uriTemplate: '/keys_new/{id}',
    shortName: 'Key_new',
    output: KeyOutput::class,
    provider: KeyOutputProvider::class,
    openapi: true,
  )]
#[ORM\Entity(repositoryClass: KeyRepository::class)]
class KeyNew {

    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column]
    public ?int $id = null;

    #[ORM\Column(length: 255)]
    private ?string $title = null;

    public function getId(): int
    {
        return $this->id;
    }

    public function getTitle(): ?string
    {
        return $this->title;
    }

    public function setTitle(string $title): self
    {
        $this->title = $title;

        return $this;
    }
}

DTO:

<?php

namespace App\Dto;
use App\State\KeyOutputProvider;
use ApiPlatform\Metadata\Get;


class KeyOutput
{
    public int $id;

    public string $title;
}

State provider:

<?php

namespace App\State;
use ApiPlatform\Metadata\Operation;
use ApiPlatform\State\ProviderInterface;
use App\Dto\KeyOutput;
use App\Repository\KeyRepository;

final class KeyOutputProvider implements ProviderInterface
{
  public function __construct(private ProviderInterface $itemProvider, private KeyRepository $keyRepository)
  {
  }

    /**
     * {@inheritDoc}
     */
    public function provide(Operation $operation, array $uriVariables = [], array $context = []) : object | array
    {
      $key =  $this->keyRepository->find($uriVariables['id']);

      $output = new KeyOutput();
      $output->id = $key->getId();
      $output->title = $key->getTitle();
      return $output;
    }

  }

output:
{ "@context": { "@vocab": "https://sf.local.com/tts-api/docs.jsonld#", "hydra": "http://www.w3.org/ns/hydra/core#", "id": "KeyOutput/id", "title": "KeyOutput/title" }, "@type": "KeyOutput", **"@id": "/tts-api/.well-known/genid/8b4f34f659946eb5666c",** "id": 1, "title": "testa" }

I want in the @id to get "/tts-api/key_new/1"

Any idea ?
