GraphQL: Query on Object field type resolve to null

[Moumouls]

Issue Description

Step to reproduce:

• Login with a user and custom auth
• then with master key execute this GraphQL Query

query findUsers {
  users {
    edges {
      node {
        id
        username
        authData
      }
    }
  }
}

Response:

{
  "data": {
    "users": {
      "edges": [
        {
          "node": {
            "id": "X1VzZXI6Q1BJV09nSnAzMQ==",
            "username": "1vNRLdDtk3p69k6y0OE2RKZxT",
            "authData": null
          }
        }
      ]
    }
  }
}

Debug:

• Keys selected by GraphQL seems ok: objectId,username,authData
• But rest API return:

[
  {
    objectId: 'CPIWOgJp31',
    username: '1vNRLdDtk3p69k6y0OE2RKZxT',
    createdAt: '2020-04-21T10:58:07.147Z',
    updatedAt: '2020-04-21T10:58:07.373Z',
    ACL: { '*': [Object], CPIWOgJp31: [Object] }
  }
]

When i disable key selection on parse server graphQL, it seems that authData is correctly returned by internal API.

Select on object type seems to be ignored
