我正在遍历特定清单组中的所有主机，以检查文件中stat输出的键值响应，但无法映射它。 有人可以提示如何映射吗？

      - debug:
          var: result
      - debug:
          msg: "FOUND: /etc/cachefilesd.conf exists..."
        when: result.results.stat.exists
        delegate_to: "{{ item }}"
        with_items: "{{ groups['gpu_node'] }}"

输出：

   TASK [services-pre-install-checks : debug]

     "result": {[0m
         "changed": false,[0m
         "msg": "All items completed",[0m

                 }[0m
