I have a pytest script making HTTP calls. One of the calls returns a response like this:

{"success":[],"error":[{"hpsId":10037,"powerPlant":{"name":"xxx","id":16606,"regionId":20,"priceArea":2,"timeSeries":null,"units":[]}}]}

The script looks like this:

def test_bid_submission_send():
# Act:
response = post_requests(token, '/xxx/api/xxx/bidsubmissions/send',
                         setpayload_bidsubmissions_send(powerplantId))

and the response is like the mentioned.

I want to fail the test_bid_submission if the error [] has content (then the success [] will have content).

How can I obtain that?
