PUT data through fos_rest.request_body ParamConverter - Symfony 3

Question

I am working on a REST API with FOS Rest Bundle and FOS User Bundle

The data being PUT to the server is:

{"id":1,"email":"email@example.com","username":"adminuser","enabled":true,"locked":false,"groups" :[]}

The routing looks okay:

admin_user_put_user PUT ANY ANY /admin/users/{id}

It is reaching this code below:

/**
 * @ParamConverter("userData", converter="fos_rest.request_body")
 * @View(statusCode=204)
 */
public function putUserAction( $id, User $userData )
{
    $this->denyAccessUnlessGranted( 'ROLE_ADMIN', null, 'Unable to access this page!' );

    $em = $this->getDoctrine()->getManager();
    $user = $em->getRepository( 'AppBundle:User' )->find( $id );
    $user->setEmail( $userData->getEmail() );
    $user->setEmailCanonical( $userData->getEmailCanonical() );
    $user->setEnabled( $userData->isEnabled() );
    $user->setLocked( $userData->isLocked() );
    $em->flush();

}

The problem is that it is not populating $userData with the data sent.

Could it be a configuration issue?

                priorities: ['json', 'html', 'xml','form']
                fallback_format: ~
                prefer_extension: true
                methods: [ 'get', 'post', 'put', 'delete']
            - { path: '^/', stop: true }

I understand the code is a little awkward and welcome suggestions for improvement.

The absence of the group data in the save code is deliberate, I'll get to that later.

Check the existence of SensioFrameworkExtraBundle and if it's configured as shown here (sensio_framework_extra and fos_rest).

Also you may try to define a class attribute, so it would map without a body converter (to see if it works):

@ParamConverter("userData", class="AppBundle:User")
