How to parse this json and fail test if error key exists?

[Sergey Dashko]

I want parse this json:

{

  "jobId": "176b159e-cc0a-41c5-9681-a17507a18c41",

  "result": "{\"error\":\"Some Error\"}"

}

I've tried it like this:

.check(status.is(200), jsonPath("$.result.error").notExists)

but seems jsonPath can't find anything in result key.

How to do what I want correctly?

Thanks in advance.
