Проблема в использовании fail_when с json_query

Question

У меня возникает проблема, когда я пытаюсь проверить, совпадает ли цель символической ссылки на удаленном сервере с локальными серверами.

Что-то не так с моей книгой воспроизведения?

@ localhost

$ ls -l /tmp/test /tmp/test2
lrwxrwxrwx 1 myuser users 11 Apr 23 15:55 /tmp/test -> test.target
lrwxrwxrwx 1 myuser users 12 Apr 23 15:56 /tmp/test2 -> test2.target

@ target

$ ls -l /tmp/test /tmp/test2
lrwxrwxrwx 1 myuser users 11  4月 23 16:05 /tmp/test -> test.target
lrwxrwxrwx 1 myuser users 12  4月 23 16:05 /tmp/test2 -> test2.target

playbook (test.yml)

- hosts: all
  gather_facts: no
  vars:
    files:
    - /tmp/test
    - /tmp/test2
  tasks:
  - stat:
      path: '{{ item }}'
    register: out_stat_source
    delegate_to: localhost
    with_items: '{{ files }}'
    run_once: true

  - stat:
      path: '{{ item }}'
    register: out_stat_remote
    failed_when: out_stat_remote.stat.lnk_target != out_stat_source|json_query(get_lnk_target)
    vars:
      get_lnk_target: |
        {{ "results[?item=='" +  item + "'].stat.lnk_target" }}
    with_items: '{{ files }}'

Ожидаемое поведение - SUCCESS, так как цель символических ссылок на удаленном сервере и локальном сервер одинаков. Однако вывод выглядит следующим образом:

вывод test.yml

Я создал следующую книгу для отладки. Я подтвердил, что results[0] работает, но results[?item=='foo'] не работает в json_query, когда я использую его с fail_when.

playbook (test2.yml)

- hosts: all
  gather_facts: no
  vars:
    files:
    - /tmp/test
    - /tmp/test2
  tasks:
  - stat:
      path: '{{ item }}'
    register: out_stat_source
    delegate_to: localhost
    with_items: '{{ files }}'
    run_once: true

  - debug:
      msg: '{{ out_stat_source|json_query(get_lnk_target) }}'
    vars:
      get_lnk_target: |
        {{ "results[?item=='" +  item + "'].stat.lnk_target" }}
    with_items: '{{ files }}'

  - stat:
      path: '{{ item }}'
    register: out_stat_remote
    failed_when: out_stat_remote.stat.lnk_target != out_stat_source|json_query(get_lnk_target)
    vars:
