Elasticsearch support Normalization error

Hi everyone, Thanks for this great work !

I’m using api-platform/core": "^2.4.0-beta.1", I followed Documentation to set up the Elasticsearch support and when I want to GET a collection with a DateTime attribute

/**
     * @var \DateTimeInterface
     *
     * @Gedmo\Timestampable(on="create")
     * @ORM\Column(name="created_at", type="datetime")
     * @Groups("timestampable_read")
     */
    private $createdAt;

I have the following issue : Cannot create an instance of DateTime from serialized data because its constructor requires parameter \"time\" to be present.

Stack trace

Symfony\Component\Serializer\Exception\MissingConstructorArgumentsException:
Cannot create an instance of DateTime from serialized data because its constructor requires parameter "time" to be present.

This is definitely a bug, we’re in the process of fixing priority issues in https://github.com/api-platform/core/pull/2495

[ismail1432]

To avoid the issue I had this in service.yaml with a priority higher than api_platform.elasticsearch.normalizer.item

  datetime_normalizer:
        class: Symfony\Component\Serializer\Normalizer\DateTimeNormalizer
        public: false
        tags:
            - { name: serializer.normalizer, priority: 9 }
