HTTP 500 error with FOSRestBundle when getting an entity with relations - php

Question

I'm starting with FOSRestBundle and when I get the values of an entity without relations and display it in the browser, I have no problem. But when I try to get an entity with relations, it shows me an error with code: 500.
Here is the code:
app/config/config.yml:
fos_rest:
routing_loader:
default_format: json
param_fetcher_listener: true
body_listener: true
format_listener: true
view:
view_response_listener: 'force'
ApiRestBundle/Controller/UserController (this works fine)
/**
* #return array
* #Rest\Get("/users")
* #Rest\View()
*/
public function getUsersAction()
{
$response = array();
$em = $this->getDoctrine()->getManager();
$users = $em->getRepository('CASUsuariosBundle:User')->findAll();
$view = $this->view($users);
return $this->handleView($view);
}
APIRestBunde/Controller/CategoryController (this doesn't works)
/**
* #return array
* #Rest\Get("/categories")
* #Rest\View()
*/
public function getCategoriesAction()
{
$response = array();
$em = $this->getDoctrine()->getManager();
$categories = $em->getRepository('CASEventBundle:Category')->findAll();
$view = $this->view($categories);
return $this->handleView($view);
}
the error code:
{"error":{"code":500,"message":"Internal Server
Error","exception":[{"message":"Notice: Undefined index:
name","class":"Symfony\Component\Debug\Exception\ContextErrorException","trace":[{"namespace":"","short_class":"","class":"","type":"","function":"","file":"C:\xampp\htdocs\CASPruebas\vendor\doctrine\orm\lib\Doctrine\ORM\Persisters\BasicEntityPersister.php","line":1758,"args":[]}...

your problem is a little bit complicated to solve.
This error code can mean a lot of different things!
But I think it is not directly a FOSRestBundle problem. Maybe you have a relation problem on your Category entity...
What is the result of this: doctrine:schema:validate
Edit : Maybe it will be more simple to solve it if you give us the full error code.
