当我使用变量时，抓取不会转移

当我使用变量并获取消息为“ msg”时，获取模块不会传输文件：“远程文件不存在，不传输，被忽略”。但是文件在源目录中退出。请提出任何错误的建议。

ansible 2.1.0.0

    - hosts: host_A
    become_user: yes
    gather_facts: no
    tasks:
    - name: list files
      shell: ls -1 /root/stuff/install.1_comiskey-v01
      register: dumpfiles 
    -debug: var=dumpfiles

    - name: fetch files 
      fetch: src={{item}} dest=/tmp/fetched/  flat=yes  
      with_items: ('{{dumpfiles.stdout_lines}}')  
      register: test
    - debug: var=test 

输出：
