API Platform version(s) affected: 3.3.12

Description
When converting from Entity ApiResource to DTOs with ApiResource and querying an API Resource which contains a OneToMany Relationship, an error is thrown by the LinksHandlerTrait which states:
The class "\App\Entity\xxx" cannot be retrieved from "\App\ApiResource\xxx" which is unexpected, as the Entity should not be retrieved from the DTO Class.
Note: This works fine using the Entity ApiResource.

Comparing the Processed Data inside the File: api/vendor/api-platform/core/src/Doctrine/Common/State/LinksHandlerTrait.php at Line 80 - 85 i could see, that the Handler is fed with resourceClass \App\Entity\xxx which is compared to \Api\Resource\xxx and obviously fails. Debugging the same Data when defining the API Resource above an Entity i could see, that \App\Entity\xxx was compared against \App\Entity\xxx which does obviously work.

How to reproduce

See my example Repository: https://github.com/KaiGrassnick/api-platform3-graphql-one-to-many-issue

Otherwise:

  1. Create an API Platform Project, add GraphQL Dependency (webonyx/graphql-php)
  2. Create 2 Entities and reference them One to Many
  3. Create 2 API Resources with stateOptions referring to the Entity ( example below )
  4. Run Query on the Resource which should contain the Array of the referenced Resources
{
  serverApiResources {
    edges {
      node {
        name
        ips {
          edges {
            node {
              ip
              public
            }
          }
        }
      }
    }
  }
}

Example API Resources:

#[ApiResource(
    graphQlOperations: [
        new Query(),
        new QueryCollection()
    ],
    provider: EntityClassDtoStateProvider::class,
    processor: EntityClassDtoStateProcessor::class,
    stateOptions: new Options(entityClass: ServerEntity::class),
)]
class ServerApiResource
{
    #[ApiProperty(readable: false, writable: false, identifier: true)]
    public ?int $id = null;

    public string $name;

    /**
     * @var IpApiResource[]
     */
    public array $ips = [];

    public function addIp(IpApiResource $ip): void
    {
        $this->ips[] = $ip;
    }

    public function removeIp(IpApiResource $ip): void
    {
        unset($this->ips[array_search($ip, $this->ips)]);
    }
}
#[ApiResource(
    graphQlOperations: [
        new Query(),
        new QueryCollection()
    ],
    provider: EntityClassDtoStateProvider::class,
    processor: EntityClassDtoStateProcessor::class,
    stateOptions: new Options(entityClass: IpEntity::class),
)]
class IpApiResource
{
    #[ApiProperty(readable: true, writable: false, identifier: true)]
    public ?int $id = null;

    public string $ip;

    public bool $public;
}

Possible Solution
I've looked into the LinksHandlerTrait File (api/vendor/api-platform/core/src/Doctrine/Common/State/LinksHandlerTrait.php), it seems that we could replace the $resourceClass ( which seems to be populated with the Entity Class ) with $context['resource_class']. If we do that, the query works just fine, but so far i have not checked any side effects regarding mutations etc.
