Errors from debops.avahi with 3.0.5 and ansible 2.15.2

[sjthespian]

I am running into an error trying to use devops.avahi with ansible 2.15.2. I'm not sure what it is complaining about, as I am not setting any avahi int values in my host or group variables, so I'm assuming this is coming from some incompatibility with the defaults in the role and the version of ansible I am running.

These are the only avahi variables I set:

avahi__enabled: True
avahi__publish_hinfo: true
avahi__publish_workstation: true
avahi__publish_device_info: true
avahi__disallow_other_stacks: False
avahi__python__dependent_packages3:
  - python3-avahi
avahi__python__dependent_packages2:
  - python3-avahi

My ansible info:

> ansible --version
ansible [core 2.15.2]
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3/dist-packages/ansible
  ansible collection location = /root/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/bin/ansible
  python version = 3.10.12 (main, Jun 11 2023, 05:26:28) [GCC 11.4.0] (/usr/bin/python3)
  jinja version = 3.0.3
  libyaml = True

And the error output with -vvvv:

It looks like it's an incompatibility between 2.12 and 2.15. Rolling back to 2.12 works.
