When I'm debugging Ansible Playbooks and I don't know if I can access a
variable I usually have a debug block.
In your case this might look something like:
#####
- debug:
msg: ''{{ item | to_nice_yaml }}'
loop: '{{ interfaces }}'
- meta: end_play
#####
Put this block in front of the failing and you'll get a view on each member of
"interfaces" as seen by Ansible. After the debug
messages the play will end gracefully.
