List of steps to reproduce (step by step, including full links if applicable):

• Using the "tester in orchestrator" patches, attempt to run tests on a function

What happens?:
The tests all fail. The pair that is returned shows that the invalid ZObject is, in fact, valid.

Example:

{
    "Z1K1": "Z22",
    "Z22K1": "Z23",
    "Z22K2": {
      "Z1K1": "Z5",
      "Z5K1": {
        "Z1K1": "Z502",
        "Z502K1": {
          "Z1K1": {
            "Z1K1": "Z9",
            "Z9K1": "Z22"
          },
          "Z22K1": {
            "Z1K1": "Z6",
            "Z6K1": "tset"
          },
          "Z22K2": {
            "Z1K1": {
              "Z1K1": "Z9",
              "Z9K1": "Z23"
            }
          }
        }
      }
    }
  }

What should have happened instead?:
The response object should have been returned instead of an error being thrown.
