我的ansible剧本无法运行，我看到找不到文件错误。但实际上文件确实存在

Question

# Replace RUNNING SERVER token by server id

- hosts: servers_app
  become_user: root
  gather_facts: True
  vars:
    - running_server_token: \@\@\@_RUNNING_SERVER_\@\@\@
  tasks:
    - name: Find app js file
      become: true
      become_user: root
      shell: "ls {{ tomcat_install_base }}/webapps/{{ deployed_appl_name }}/app/app-*.js"
      register: app_js
    - debug: msg="{{ app_js.stdout }}"
    - name: Replace RUNNING SERVER token by server id
      become: true
      become_user: root
      replace:
        path: "{{ app_js.stdout }}"
        regexp: "{{ running_server_token }}"
        replace: "{{ inventory_hostname }}"

当我运行上述剧本时，我看到以下错误消息。我可以知道我是否做错了事。

所有js文件确实存在，但不确定为什么总是显示此消息。
