RuntimeError: There is no current event loop in thread 'MainThread'.

In the example below, get_all_performed_trainings.py is a straight copy from the examples folder, with USERNAME, PASSWORD, and FILENAME set as appropriate.

~/dev/fl-test % python3 get_all_performed_trainings.py
Traceback (most recent call last):

    raise RuntimeError('There is no current event loop in thread %r.'
RuntimeError: There is no current event loop in thread 'MainThread'.

It's worth noting that the code did output a JSON file with some training data. I have no idea whether it has all of the data or not.

Other details:

~/dev/fl-test % python3 --version
Python 3.9.6

Thank you for reporting this issue. It seams to be a bug in setting a async lock without having an event loop.

You can use my example and remove lines 42 - 71 and 77 - 78. This would run only the async code which should work.

Commenting out just line 78 seemed to work. Thanks!
