获取Ansible运行时错误字典对象，尽管变量不为null，也没有属性'stdout_lines'

Question

下面是我的剧本，它的变量running_processes包含一个pids列表（一个或多个）

[接下来，我读取每个PID的用户ID。到目前为止一切都很好。

然后，当我收到错误消息时，我尝试使用curr_user_ids在-debug module变量中打印用户ID列表：'dict object'没有属性'stdout_lines'

我期望curr_user_ids包含一个或多个条目，从下面共享的输出中可以明显看出。

    - name: Get running processes list from remote host
      shell: "ps -few | grep java | grep -v grep | awk '{print $2}'"
      changed_when: false
      register: running_processes

    - name: Gather USER IDs from processes id before killing.
      shell: "id -nu `cat /proc/{{ running_processes.stdout }}/loginuid`"
      register: curr_user_ids
      with_items: "{{ running_processes.stdout_lines }}"

    - debug: msg="USER ID LIST HERE:{{ curr_user_ids.stdout }}"
      with_items: "{{ curr_user_ids.stdout_lines }}"

您能否建议我为什么会收到错误以及如何解决该错误？

谢谢

变量curr_user_ids记录每次迭代的结果

register: curr_user_ids
with_items: "{{ running_processes.stdout_lines }}"

结果列表存储在

curr_user_ids.results

看看变量

- debug:
    var: curr_user_ids

并循环输出stdout_lines

- debug:
    var: item.stdout_lines
  loop: "{{ curr_user_ids.results }}"
