Question about planning ... failures?

I took the jupyter notebook from the repo (which is, I think, the same as the python script in the README) and modified it slightly (print the URL and the response from celery) to test my PaaS server. I'm getting a very odd result:

```
Service URL is http://lacrosse-0:5001/package/lama-first/solve
Computing...
{'result': {'call': 'timeout 20 planutils run lama-first -- domain problem',
'output': {},
'output_type': 'generic',
'stderr': '',
'stdout': ''},
'status': 'ok'}
```
So no plan, but no error output, either, and celery seems to be claiming my request is no longer `PENDING`.

Is this what I should expect if there's a time out?

Is there a log I should be looking at to diagnose this?
