'NoneType' object has no attribute 'preferred_address'

[Giuseppe Barichello]

When I click on a list name (as admin), I get:

Internal Server Error: /mailman3/postorius/lists/mylist/

AttributeError at /postorius/lists/mylist/
'NoneType' object has no attribute 'preferred_address'

This happens after upgrading my server from Debian bullseye to Debian bookworm.

The complete error log is attached.

TIA

This appears to be a Debian issue which should be reported at https://bugs.debian.org/mailman3-web

Thankyou Mark,
