Deserialize return array

[dev-yann]

Hi, I would like to perform a recursive deserialization. But the problem is that the function return an array instead of object.
services.yaml =>

  # Add DateTime Normalizer to Dunglas' Doctrine JSON ODM Bundle
    dunglas_doctrine_json_odm.serializer:
        class: Dunglas\DoctrineJsonOdm\Serializer
        arguments:
            - ['@dunglas_doctrine_json_odm.normalizer.array', '@serializer.normalizer.datetime', '@dunglas_doctrine_json_odm.normalizer.object']
            - ['@serializer.encoder.json']
        public: true

$userOrder = $serializer->deserialize($request->getContent(), UserOrder::class, 'json');

$userorder is an array instead of object.

this is my entity =>

<?php

namespace App\Entity;

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Serializer\Annotation\MaxDepth;

/**
 * @ORM\Entity
 */
class UserOrder
{
    /**
     * @ORM\Id()
     * @ORM\GeneratedValue(strategy="UUID")
     * @ORM\Column(type="guid", unique=true)
     */
    private $id;

    /**
     * @ORM\Column(type="boolean", nullable=true)
     */
    private $status;

    /**
     * @var OrderDetail[] | ArrayCollection
     * @ORM\OneToMany(targetEntity=OrderDetail::class, mappedBy="order", orphanRemoval=true, cascade={"persist"})
     */
    private $orderDetails;
....

I can get an object with this instruction in my controller :

$normalizer = new ObjectNormalizer(null, null, null, new ReflectionExtractor());
$serializer = new Serializer([new ArrayDenormalizer(), $normalizer], [new JsonEncoder()]);
$userOrder = $serializer->deserialize($request->getContent(), UserOrder::class, 'json');

But I would like to use the serializer service directly, is there any way for perform a recursive deserialization with doctrine-json-odm and get real object, not an array ? Thanks for your time
