When you make an invalid request, you’ll receive a response with an “errors” object.

{
  "error": {
    "errors": [
      {
        "message": "Unknown argument \"trackedShipment\" on field \"deleteTrackedShipments\" of type \"Mutation\". Did you mean \"trackedShipments\"?",
        "locations": [
          {
            "line": 2,
            "column": 26
          }
