Hello,

The latest affected job is using ansible-lint-6.12.1 [1]. Last good was using ansible-lint-6.11.0.

ansible-6.12.0/.1 was recently released(4 days ago): https://github.com/ansible/ansible-lint/releases. 6.12.0 is affected as well.

I was able to reproduce the issue locally with the latest ansible-lint 6.12.1:

Passes with ansible-lint 6.11.0
~~~
$ ansible-lint --version
ansible-lint 6.11.0 using ansible 2.14.2

A new release of ansible-lint is available: 6.11.0 → 6.12.1
