We are using GraphQL using apollo-server, and we are trying to execute multiple queries in a single query operation as described below.

I expect that both queries should execute and provide their results.

query Operation1 {
 getPosts: {
   id
   title
   url
 }
 getBooks: {
   id
   title
 }
}

Now in the above case, if both queries are successful, then we are getting results for both given below.

{
  "data": {
    "getPosts": [{
      "id": "P1",
      "title": "post1",
      "url": "/blog/post1"
    }],
    "getBooks": [{
      "id": "B1",
      "title": "book1"
    }]
  }
}

But if in case any of query fails, the result is only represented as errors.

{
  "data": {},
  "errors": [
    {
      "message": "failure message",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "getBooks"
      ],
      "extensions": {
        "code": "INTERNAL_SERVER_ERROR"
      }
    }
  ]
}

I am not sure if this is the desired behavior, because my expectation was as follows.

{
  "data": {
    "getPosts": [
      {
        "id": "P1",
        "title": "post1",
        "url": "/blog/post1"
      }
    ],
    "getBooks": {
      "data": {},
      "errors": [
        {
          "message": "failure message",
          "locations": [
            {
              "line": 2,
              "column": 3
            }
          ],
          "path": [
            "getBooks"
          ],
          "extensions": {
            "code": "INTERNAL_SERVER_ERROR"
          }
        }
      ]
    }
  }
}
