voryx_entity form type don't work

[amsolucionesweb]

I post this json with angularjs

{
"name":"mason inc"
"status": {
        "id": 1
        "name": "Enable"
    }
}

My form is:

$builder
            ->add('name')
            ->add('status', 'voryx_entity', array(
                    'class' => 'AppBundle\Entity\Status',
                )
            )
;

And Response is:

{
   "errors":{
      "form":{
         "children":{
            "name":{

            },
            "status":{
               "errors":[
                  "The selected entity does not exist"
               ]
            }
         }
      },
      "errors":[

      ]
   }
}

What is the error ?, because DataTransformer provide in line 55

 if (is_array($data) && isset($data['id'])) {
            return $data['id'];
        }

Symfony version: 2.8.6 and de entity 1 exists in the data base.
