Possible race condition between startup and shutdown

[hmol]

I'm Im getting this error often:
JobLookupError 'No job by the id of 5b5a4fcd3cf742b0a97cc9dfcbc47d1d was found'
Could it be a race condition between startup and shutdown? See stack trace below:

Hey @hmol, what version of the Python SDK are you running?
