There is a PR for an az facts module open at the moment which is able to
return the available AZ's
https://github.com/ansible/ansible/pull/20690
It will allow you to test what az's might exist. Otherwise I'd follow up on
what has already been said to see what keys have been included with the
registered variable, aws_current_az
- name: Show contents of aws_current_az
debug:
var: aws_current_az
