named: Zone definitions disappeared after upgrading ansible-core to 2.19

[brlin-tw]

SUMMARY

After upgrading Ansible to >=2.19 the zone definitions are missing from the generated named.conf file.

STEPS TO REPRODUCE

1. Upgrade your Ansible installation to 2.19.
2. Deploy as usual.
3. Check the content of the installed named.conf file

EXPECTED RESULTS

Zone definitions are available in the named.conf file.

ACTUAL RESULTS

No zone definitions are available.

In my specific play, my task failed with the following error due to the missing definition:

There's also a weird warning message in an earlier task:

WORKAROUNDS

Downgrade the ansible-core package to 2.18:

pipx inject ansible ansible-core==2.18

According to my testing, 2.16 also works.
