This response representation is inconsistent with actual task representation.
There are not variables rendered.

Replication Steps

create APP with basic process (start > user task > end) and publish it with process
start process instance

use the REST API and add a "local" variable to the user task

POST http://localhost:9999/activiti-app/api/enterprise/tasks/107520/variables
[
  {
    "name": "tasktestvar2",
    "scope": "local",
    "type": "string",
    "value": "toastysnoot"
  }
]

Response (200):

[
  {
    "name": "tasktestvar2",
    "type": "string",
    "value": "toastysnoot",
    "scope": "local"
  }
]

Use the REST API to query for list of tasks

POST http://localhost:9999/activiti-app/api/enterprise/tasks/query
{
  "taskId":107520
}

Response (200)

{
  "size": 1,
  "total": 1,
  "start": 0,
  "data": [
    {
      "id": "107520",
      "name": "Task With Variables",
      "description": null,
      "category": "snicker",
      "assignee": {
        "id": 1003,
        "firstName": "Warden1",
        "lastName": "JailBird",
        "email": "warden1.jailbird@foo.com",
        "externalId": "warden1"
      },
      "created": "2018-11-16T18:04:10.536+0000",
      "dueDate": null,
      "endDate": null,
      "duration": null,
      "priority": 100,
      "parentTaskId": null,
      "parentTaskName": null,
      "processInstanceId": "107515",
      "processInstanceName": null,
      "processDefinitionId": "TaskMeVariables:2:107514",
      "processDefinitionName": null,
      "processDefinitionDescription": null,
      "processDefinitionKey": null,
      "processDefinitionCategory": null,
      "processDefinitionVersion": 0,
      "processDefinitionDeploymentId": null,
      "formKey": null,
      "processInstanceStartUserId": null,
      "initiatorCanCompleteTask": false,
      "adhocTaskCanBeReassigned": false,
      "taskDefinitionKey": "taskvar",
      "executionId": "107515",
      "memberOfCandidateGroup": false,
      "memberOfCandidateUsers": false,
      "managerOfCandidateGroup": false
    }
  ]
}

Actual Behavior

POST task query response 'task representations' do not list task's variables

Expected Behavior

POST task query response 'task representations' should list task's variables as per the api-explorer document example

Workaround

For each task in the list, you can use the GET task variable REST API call to get local, global or both types variables for each task
```
GET http://<host>:<port>/activiti-app/api/enterprise/tasks/<taskid>/variables?scope=local 
```

(api-explorer) http://localhost:9999/activiti-app/api-explorer.html#!/task-variables/getVariablesUsingGET

Additional Information

There are local and global variables, if variables are to be rendered per task representation this could be excessive if the global variables (proc var) are also listed.
