No converter named 'fos_rest.request_body' What's the problem?

Question

symfony

I want to receive an object at the input of the method, but the exception takes off
No converter named 'fos_rest.request_body' found for conversion of parameter 'article'.
What is the problem? Do I need to describe the converter somewhere?
Controller code

<?php
namespace MyBundle\Controller\API\V1;

class OrganizationController extends FOSRestController
{
    /**
     * @param Article $article
     * @return Response
     * @ParamConverter("article", converter="fos_rest.request_body")
     */
    public function postDTOAction(Article $article = null)
    {
    }
}
