JMS Serializer Annotation Group not working on Entity using Symfony 4

I have been using the Group annotation for years on SF2 and SF3. I'm trying SF4.1. And I'm getting an empty JSON when I send a GET to my endpoint.

The interesting parts of my composer.json:

 "friendsofsymfony/rest-bundle": "^2.3",
 "jms/serializer-bundle": "^2.3",
 "sensio/framework-extra-bundle": "^5.1",
 "symfony/serializer-pack": "^1.0"

The config:

framework:
    serializer:
       enabled: true
       enable_annotations: true

sensio_framework_extra:
    view: { annotations: true }

fos_rest:
   routing_loader:
        default_format: json

   view:
        view_response_listener: 'force'

   format_listener:
        rules:
               - { path: ^/, prefer_extension: true, fallback_format: json, priorities: [ json,xml, html  ] }

The Entity

use JMS\Serializer\Annotation\Groups;

class User implements UserInterface, \Serializable
{

private $id;

/**
 * @Groups({"api"})
 */
private $username;

And the endpoint API Controller:

use FOS\RestBundle\Controller\FOSRestController;
use FOS\RestBundle\Context\Context;
use FOS\RestBundle\View\View;

class UserController extends FOSRestController {

public function getUserAction(Request $request, EntityManagerInterface $em)
{
    $user = $em->getReference('App:User', 1);
    $view = View::create();
    $context = new Context();
    $context->setGroups(['api']);
    $view->setContext($context);
    $view->setData($user);
    return $this->handleView($view);
 }
}

If I remove `$context->setGroups(['api']), the JSON has all the User attributes.

Any idea? Thanks!

By default FOSRest prefers the JMSSerializer if it is installed. So first check if the service defined by the JMSSerializerBundle is defined:

./bin/console debug:container jms_serializer.serializer

If this command displays an error message (ServiceNotFound) then the bundle is not correctly installed. Check the config/bundles.php and add the following line if it's missing:

JMS\SerializerBundle\JMSSerializerBundle::class => ['all' => true],

If it actually is installed, you can check the fos_rest configuration, if it maybe changes the serializer service. You can configure it like that:

fos_rest:   
    service:
        serializer: "fos_rest.serializer.jms"
