SINE EXAMPLE ERROR

[JCMiles]

Hi,
I'm trying to run the sine_experiment.py experiment:

but I get stuck with this error:

Seems liek jobInfo.results is None and that crashes when:
results = json.loads(jobInfo.results)

I also tried with a personal dataset and got the same error
Any idea on what's the cause and how to fix it?
