Actually it might be a bug in my branch where even though job submission fails, an http status code of 201 is being returned.

We chatted offline and @dposada suggested there is room for improvement here by not claiming success if the UUID is not found in the response.

Not sure if this is worth handling unless we think it could happen in the current master code
