Error: 'backports.zoneinfo.ZoneInfo' object has no attribute 'zone'

I’m getting an error message when trying to iterate though the calendar events. it then breaks out and give me no data.

Python Version: Python 3.7.3 Installed Version: O365-2.0.14 Host System: Raspberry Pi (Buster)

Calling Code:

     o365_mycalendar = Account.schedule().get_default_calendar()
     o365_mycalendarEvents = o365_calendar.get_events(limit=20, query=o365_calendarQuery, include_recurring=True)
     for o365_event in o365_mycalendarEvents:
          print('E  ', o365_event.start, o365_event.end, o365_event.subject)

Stack Trace

AttributeError: 'backports.zoneinfo.ZoneInfo' object has no attribute 'zone'

I’m guessing I have a problem somewhere else (ie a system dependency that is not installed), but can’t track down.

I also solved this issue after tzlocal downgrade

pip install tzlocal==2.1

[mw-deb]

Workaround: It helped me to manually install tzlocal on version 2.1.
