Unsuccessful requests come as empty

Issue

When a failed Query goes to Quickbase and we get a unsuccessful query, we got null for the error response. Basically QB returned 0 results but the status code was 200.

How to Reproduce

Create a request that you know will return 0 results in Quickbase.

{
  "data": [],
  "fields": [
    {
      "id": 1,
      "label": "Date Created",
      "type": "timestamp"
    },
    {
      "id": 2,
      "label": "Date Modified",
      "type": "timestamp"
    },
    {
      "id": 3,
      "label": "Record ID#",
      "type": "recordid"
    }
  ],
  "metadata": {
    "numFields": 3,
    "numRecords": 0,
    "skip": 0,
    "totalRecords": 0
  }
}

Then try to use it like normal.

// Let' say this query will fail and isSuccess will be false
var (response, errorResponse, isSuccess) = await quickbaseClient.QueryRecords(qbQuery);

// errorResponse is null! So then this will almost act like a succesful query! not good...
