FOSRestBundle returning empty content - php

Question

I'm implementing FOSUserBundle in my project. I want a basic GET action to return a json object of the ContactList entity.
Controller:
class ContactListController extends FOSRestController
{
use ViewContextTrait;
const DEFAULT_GROUPS = ['organization_list'];
/**
* #ParamConverter("contactList", class="SchemaBundle:ContactList")
* #param ContactList $contactList
* #return Response
*/
public function getAction(ContactList $contactList)
{
return $this->handleView($this->viewWithContext($contactList, Response::HTTP_OK));
}
Trait:
use FOS\RestBundle\Context\Context;
use FOS\RestBundle\View\View;
trait ViewContextTrait
{
public function viewWithContext($data, $statusCode = null, $groups = self::DEFAULT_GROUPS)
{
$context = new Context();
$context->setGroups($groups);
return View::create($data, $statusCode)->setContext($context);
}
}
My config.yml:
fos_rest:
routing_loader:
include_format: false
body_listener:
array_normalizer: fos_rest.normalizer.camel_keys
param_fetcher_listener: true
view:
view_response_listener: 'force'
format_listener:
rules:
- { path: '^/api', priorities: ['json'], fallback_format: json, prefer_extension: false }
The problem: When I call this route via postman (/api/contact-list/1), I always get a {} for my content in the Response object.
This is the dumped response:
What am I missing in order to return the serialized ContactList entity w/ the context group in my Response?

Solution:
First of all, my annotations weren't included. I had to add this to my config.yml:
framework:
serializer:
enabled: true
enable_annotations: true
Next, I forgot I had previously included JMS serializer into my project awhile back. Apparently the ViewHandler for the Rest Bundle has a default order of serializer services that it uses. I ended up having to include this in my config.yml:
fos_rest:
service:
serializer: fos_rest.serializer.symfony
By default, FOSRest was using JMS Serializer which wasn't configured properly.
