Error with Model Attribute

[AdrienBr]

Hello,
Symfony version : 5.4
Bundle version : 4.22.1

When I use this attribute :

    use OpenApi\Attributes as OA;
    use Nelmio\ApiDocBundle\Annotation\Model;

    ...

    #[OA\Response(
        response: 200,
        description: "Lorem Ipsum",
        content: new OA\JsonContent(
            ref: new Model(type: MyEntity::class, groups: ['openapi'])
        )
    )]

I get this error :

Argument 3 passed to Nelmio\\ApiDocBundle\\ModelDescriber\\ObjectModelDescriber::__construct() must be an array of Nelmio\\ApiDocBundle\\PropertyDescriber\\PropertyDescriberInterface or a single Nelmio\\ApiDocBundle\\PropertyDescriber\\PropertyDescriberInterface.

Is there anything wrong with my usage of OA attribute ?

Thanks

Could you perhaps try dumping dd() the argument by manually changing the class inside ur vendor (assuming it's happening on your local running version)?

This should not be happening so I'm quite curious about what value is being passed on your end.

Hello @DjordyKoert i'm a colleague of @AdrienBr , here's the dump you asked for :

The RewindableGenerator object is made up of all the PropertyDescriber classes:

• ArrayPropertyDescriber
• BooleanPropertyDescriber
• CompoundPropertyDescriber
• DateTimePropertyDescriber
• DictionaryPropertyDescriber
• FloatPropertyDescriber
• IntegerPropertyDescriber
• NullablePropertyDescriber
• ObjectPropertyDescriber
• PropertyDescriber
• RequiredPropertyDescriber
• StringPropertyDescriber

Thanks

@DjordyKoert there's still a problem despite your fix :

{"type":"https:\/\/tools.ietf.org\/html\/rfc2616#section-10","title":"An error occurred","status":500,"detail":"Attempted to call an undefined method named \"supports\" of class \"Symfony\\Component\\DependencyInjection\\Argument\\RewindableGenerator\"."}

I think the ObjectModelDescriber's describeProperty method also needs to be modified for this to work

[DjordyKoert]

Just to be curious, may I ask if you are manually defining the nelmio_api_doc.object_model.property_describer or nelmio_api_doc.model_describers.object service?

I think the ObjectModelDescriber's describeProperty method also needs to be modified for this to work

Done, could you check again? :)

[MaximeLemolt]

@DjordyKoert yes we do manually defining the service :

    Nelmio\ApiDocBundle\ModelDescriber\ObjectModelDescriber:
        arguments:
            $mediaTypes: [ ]
            $propertyDescribers: !tagged_iterator nelmio_api_doc.object_model.property_describer
            $nameConverter: '@serializer.name_converter.camel_case_to_snake_case'
        tags: [ nelmio_api_doc.model_describer ]

I checked again, and this time everything worked fine. Thanks
