I'd like to work on solving this issue. I'm new here so could you please guide me on how to begin. Thanks in advance.

Thanks for offering.

To explain how to fix the issue I've looked at the traceback message, the source code near line 624, the entire function, the entire log reported, and then considered the message in relation to the previous messages in the same log.

The traceback was a consequence of the Journal failing to start. In turn the Journal failed because the Datastore failed. The Datastore failed because the Journal sent a limit as a floating-point value instead of an integer. In turn this was use of / instead of // after porting to Python 3.

Since the traceback happened, we have fixed the cause and made a new release.

So the only remaining thing to do is to close this issue with an explanation. Thanks for getting me to look at it! 😁
