    {
      "locations": [
        {
          "column": 5,
          "line": 12
        }
      ],
      "message": "Null value resolved for non-null field `target`"
    },
    {
      "locations": [
        {
          "line": 12,
          "column": 5
        }
      ],
      "message": "Null value resolved for non-null field `target`"
    }
  ]
}

Expectation

There are no null values for target. This may need to be hardcoded for certain platforms.
