Your points lead me to this article:
https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#formatting-data-yaml-and-json
Which notes the difference with default width of 80 with pyyaml. I changed
the width to 2147483647 on the "to_nice_yaml":
- debug:
msg: "{{ lookup('template','test.j2') | from_yaml | to_nice_yaml(indent=2,
sort_keys=False, width=2147483647) }}"
and now I see the same output from 2.11 and 2.12.
Thank you for the quick support!
