COPY failing

I’ve made a playbook that was copying files from one host to an other. Till yesterday, that started failing.

After Paying the task says:
TASK [Deployment Application] ************
changed: [192.168.214.99] => {“changed”: true}

But the result doesn’t look as a proper copy. Here’s the debug

TASK [debug] *******************
ok: [192.168.214.99] => {
“result”: {
“changed”: true,
“diff”: ,
“failed”: false
}
}

The offending snippet is

  • name: Deployment Application
    copy:
    src: /source?file
    dest: /source/files/deploys
    group: jboss
    owner: jboss
    follow: yes
    backup: yes
    register: result

Any idea is welcome, it’s my first steps in ansible

Your indentation does not look correct,can you confirm that the below is the play you’re running
