从远程服务器到Ansible主机的Ansible复制失败

我需要将最新的日志文件从远程linux服务器复制到ansible主机。这就是我迄今为止所尝试的

- hosts: [host]
  remote_user: root
  tasks:
  - name: Copy the file
    command: bash -c  "ls -rt | grep  install | tail -n1"
    register: result
    args:
      chdir: /root
  - name: Copying the file
    copy:
      src: "/root/{{ result.stdout }}"
      dest: /home

但是我得到了以下错误

TASK [Gathering Facts] ********************************************************************************************************************************************************************************************

但那个文件就在那里。请帮我解决这个问题

Ansible Copy将文件从Ansible主机复制到远程主机。改为使用Ansible fetch。

这一个有效，我必须使用fetch而不是copy从远程获取文件

 - name: Copy the file
    command: bash -c  "ls -rt | grep  install | tail -n1"
    register: result
    args:
      chdir: /root
  - name: Copying the file
    fetch:
      src: "/root/{{ result.stdout }}"
      dest: /home
      flat: yes
