AttributeError: 'NoneType' object has no attribute 'convert' with ZoneInfo #646
Description
- I am on the latest Pendulum version.
- I have searched the issues of this repo and believe that this is not a duplicate.
- OS version and name: 4.19.128-microsoft-standard Linux
- Pendulum version: 2.1.2
Issue
Reproducible example
import pendulum
from zoneinfo import ZoneInfo
tz = ZoneInfo("Europe/London")
my_datetime = pendulum.now()
my_datetime.astimezone(tz) # AttributeError: 'NoneType' object has no attribute 'convert'
Description
The above error seems to be thrown when calling pendulum.astimezone() with a ZoneInfo timezone. We are in the process of migrating a project from pytz to zoneinfo. The above example works perfectly if pendulum is replaced with datetime.datetime.
Thanks for reading and looking into this!
Expected behaviour
For pendulum.astimezone() to successfully convert a datetime object with a ZoneInfo timezone.

I stubbed by toes hard on this bug, and here it's been fixed for 8 months. Would be supremely grateful for a new release. 🙇♂️

this happens also when upgrading Django 3.x to 4.x since Django 4.x is using zoneinfo as default timezone implementation.
just following this to know when its fixed
