Ansible 'when' condition not returning results from array

Question

Facing an issue with ansible when condition. The register returns a json array list but 'when' condition won't work. Will explain what i am facing here:

First i register the directories:

- name: check if log dir exists
  win_stat:
    path: some\path
  register: register_some_dir

This is the register output:

"changed": false,
"register_some_dir": {
    "msg": "All items completed",
    "changed": false,
    "results": [
        {
            "_ansible_parsed": true,
            "stat": {
                "isdir": true,

With json filter i can filter the path like:

- set_fact:
    log_paths: "{{ register_some_dir | json_query('results[*].stat.path') }}"
  when: register_some_dir.results[*].stat.exists == true

set_fact module returns the path perfectly whithout the when condition.

But 'when' condition doesn't accept the [*] it says that it is unexpected. But it is required for an array.

if i remove the [*] from the when condition it says that 'stat' has no arrtibuut.

How can i set the when condition to work

You would have to loop through your result and test each individual element in your when condition.

Fortunately, you can do what you want by integrating the filter in a single jsmepath expression in your json_query

- set_fact:
    log_paths: "{{ register_some_dir | json_query('results[?stat.exists].stat.path') }}"
