'json_query' returns 'False' when the parameter is not defined. 'set_fact'
before the evaluation to register the variable with 'hostvars'. For example
- set_fact:
parent: "{{ parent }}"
- fail:
msg: "mandatory variable {{ item }} not passed as extra args"
when: not hostvars[inventory_hostname]|json_query(item)
loop:
- parent
- parent.child1
- parent.child2
