symfony4 - Symfony is not setting entity from post call with form using Fos Rest Bundle and Nelmio Api doc with symfony 4.4

Question

I'm trying to set an entity using a symfony form in a post http call using fos rest bundle and nelmio api doc.

I configured the form without name and configured nelmio api doc with "application/x-www-form-urlencoded"

The problem is:

After make submit form the object is not hydrateted/setted, quantity property is null!

This is my code:

fos rest configuration:

fos_rest:
    param_fetcher_listener: true
    body_listener: true
    format_listener:
        rules:
            - { path: ^/api/, priorities: [ html, json, xml ], fallback_format: ~, prefer_extension: true }
            - { path: '^/', priorities: [ 'html', '*/*' ], fallback_format: html, prefer_extension: true }
    view:
        view_response_listener: 'force'

Form:

class CartItemFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
               ->add(
                'quantity',
                IntegerType::class,
                [
                    'required' => true
                ]
            );
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults(
            [
                'data_class' => CartItem::class,
                'csrf_protection' => false,
                'allow_extra_fields' => true,
            ]
        );
    }

    /**
     * @return string
     */
    public function getName()
    {
        return '';
    }
}

Cart Manager:

class CartManager
{

    protected ObjectManager $em;

    protected ValidatorInterface $validator;

    protected FormFactoryInterface $formFactory;


    public function __construct(ObjectManager $em, ValidatorInterface $validator, FormFactoryInterface $formFactory)
    {
        $this->em = $em;
        $this->validator = $validator;
        $this->formFactory = $formFactory;
    }

    public function post(Request $request, Product $product)
    {
        $form = $this->createForm(CartItemFormType::class, new CartItem());
        $form->submit($request->request->all());
        if ($form->isValid()) {
            /** @var CartItem $cartItem */
            $cartItem = $form->getData();
            $cartItem->setProduct($product);
            $this->em->persist($cartItem);
            $this->em->flush();

            return $cartItem;
        }

        return $form;
    }

    private function createForm($type, $data = null, array $options = [])
    {
        return $this->formFactory->createNamed('', $type, $data, $options);
    }
}

Controller with nelmio api and fos rest annotation configuration.

/**
 * @RestRoute("/cart-item")
 */
class CartItemController extends AbstractFOSRestController
{

    /**
     * @RestPost("/product/{id}/")
     *
     * @RestView()
     * @SWGPost(consumes={"application/x-www-form-urlencoded"})
     *
     * @SWGResponse(
     *     response=201,
     *     description="Post Cart Item by product"
     * )
     * @SWGParameter(
     *         name="formData",
     *         in="body",
     *         description="description",
     *         @Model(type=CartItemFormType::class)
     *     )
     *
     * @SWGTag(name="Cart item")
     */
    public function postCartItemAction(Request $request, Product $product, CartManager  $cartManager)
    {
        $result = $cartManager->post($request, $product);

        return ['result' => $result];
    }
}
