how to set roles datafixtures in hautelook alicebundle?

Question

I'm having a hard time to fix this problem by adding roles in datafixtures using hautelook bundle. I create a provider that will add a roles to the fixtures

<?php

namespace AdminBundle\DataFixtures\Faker\Provider;
use AppBundle\Entity\AdminUserTypes;

class Roles
{
    public function roleAdvocate(){

        return ['ROLE_ADMIN', 'ROLE_ADVOCATE'];
    }
}

in my datafixtures yml i have this code

AppBundle\Entity\AdminUser:
    adminuser_101:
        username: '<username()>'
        email: '<email()>'
        adminUserType: 2
        enabled: true
        roles: '<roleAdvocate()>'

when the time the I run the phpunit, i always get this result error from roles

  Warning: in_array() expects parameter 2 to be array, null given

I have no idea now on how to fix it. Even I tweak the array. I get an error. I have this link but it doesn't work either. same result

In my project. I create another Entity called AdminUser Entity. This entity I inherit the abstract class User

class AdminUser extends User

Then I realize I forgot to add this method to inherit the parents constructor.

 public function __construct()
    {
        parent::__construct();
    }
