Steps to Reproduce

Run the following query against the Strawberry Graphql endpoint:

    assigned_object {
      __typename
      ... on InterfaceType {
        id
        name
        device {
          name
        }
      }
      ... on FHRPGroupType {
        id
        name
      }
      ... on VMInterfaceType {
        id
        name
      }
    }
  }
}

Expected Behavior

The expected results are returned:

{
  "data": {
    "ip_address_list": [
      {
        "id": "1",
        "assigned_object": {
          "__typename": "InterfaceType",
          "id": "1",
          "name": "GigabitEthernet0/0/0",
          "device": {
            "name": "test"
          }
        }
      },
      {
        "id": "2",
        "assigned_object": null
      }
    ]
  }
}

Observed Behavior

An error response is returned:

{
  "data": null,
  "errors": [
    {
      "message": "Cannot return null for non-nullable field IPAddressType.assigned_object.",
      "locations": [
        {
          "line": 4,
          "column": 5
        }
      ],
      "path": [
        "ip_address_list",
        2,
        "assigned_object"
      ]
    }
