Describe the bug

I took the example given in the documentation and just changed the authorization to owner

const schema = a.schema({
  Member: a.model({
    name: a.string().required(),
    // 1. Create a reference field
    teamId: a.id(),
    // 2. Create a belongsTo relationship with the reference field
    team: a.belongsTo('Team', 'teamId'),
  })
  .authorization(allow => [allow.owner()]),

  Team: a.model({
    mantra: a.string().required(),
    // 3. Create a hasMany relationship with the reference field
    //    from the `Member`s model.
    members: a.hasMany('Member', 'teamId'),
  })
  .authorization(allow => [allow.owner()])
});

I can run a mutation for creating a team with success.

mutation CreateTestTeam {
  createTeam(input: {mantra: "Test"}) {
    id
  }
}

But when I run this mutation

mutation CreateJohn {
  createMember(input: {name: "John", teamId: "c0da8ec0-5fe9-4125-b62c-1b0dbcb4a557"}) {
    id
    name
    team {
      id
      mantra
    }
  }
}

This is what I get

{
  "data": {
    "createMember": {
      "id": "16827537-b102-40f5-83e9-252a65872cda",
      "name": "John",
      "team": null
    }
  },
  "errors": [
    {
      "path": [
        "createMember",
        "team",
        "id"
      ],
      "locations": null,
      "message": "Cannot return null for non-nullable type: 'ID' within parent 'Team' (/createMember/team/id)"
    },
    {
      "path": [
        "createMember",
        "team",
        "mantra"
      ],
      "locations": null,
      "message": "Cannot return null for non-nullable type: 'String' within parent 'Team' (/createMember/team/mantra)"
    }
  ]
}

Note:
Running the query just after

query GetTeam {
  getTeam(id: "c0da8ec0-5fe9-4125-b62c-1b0dbcb4a557") {
    id
    mantra
    members {
      items {
        id
        name
      }
    }
  }
}

works (aka John was created, but the response had an error)

{
  "data": {
    "getTeam": {
      "id": "c0da8ec0-5fe9-4125-b62c-1b0dbcb4a557",
      "mantra": "Test",
      "members": {
        "items": [
          {
            "id": "16827537-b102-40f5-83e9-252a65872cda",
            "name": "John"
          }
        ]
      }
    }
  }
}

Also, when I run

query GetJohn {
  getMember(id: "16827537-b102-40f5-83e9-252a65872cda") {
    id
    name
    team {
      id
      mantra
    }
  }
}

There are no issues

{
  "data": {
    "getMember": {
      "id": "16827537-b102-40f5-83e9-252a65872cda",
      "name": "John",
      "team": {
        "id": "c0da8ec0-5fe9-4125-b62c-1b0dbcb4a557",
        "mantra": "Test"
      }
    }
  }
}

Expected behavior

When using allow.authenticated() I do not have this issue. I expect the same behavior when auth is owner()

Reproduction steps

Simply creating a new model with team and member like in the documentation, but with owner for the auth for both team and member

Hey,👋 thanks for raising this! I'm going to transfer this over to our API repository for better assistance 🙂

[ipodishima]

Perfect thanks

I’m just seeing this in the documentation

maybe it’s kinda related

[AnilMaktala]

Hey @ipodishima, Thanks for raising this. As mentioned in the documentation, you need to query the relation data separately.

[ipodishima]

Ok @AnilMaktala
It’s a bit weird though, because the documentation is not really clear about this nor does it specify how you can create a member in this case.
By default, the mutation query to create a member tries to return the team.
So maybe that it shouldn’t be the case somehow?

Hey @ipodishima, Are you using subscriptions in your app? If not, you can disable them to resolve this issue.
