title: Tower: What is causing "[WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details"
body: <p>I am just starting to work with Ansible Tower and made a project and then a job template under that project that uses a small initial test playbook (Test.yml):</p>
  <pre><code>---
  - hosts: east01.xxxxx.com
    become: yes
    become_method: sudo
  
    tasks:
    - name: test
      shell: echo 'line one line two line three' &gt;&gt; /tmp/abcdef.txt
  </code></pre>
  <p>and, when I try to run that playbook by clicking the &quot;rocketship&quot; in Tower, it looks like it is working:</p>
  <pre><code>Identity added: /tmp/awx_35003_yehjodc1/artifacts/35003/ssh_key_data (/tmp/awx_35003_yehjodc1    /artifacts/35003/ssh_key_data)
  [WARNING]: Invalid characters were found in group names but not replaced, use
  -vvvv to see details
  PLAY [east01.xxxxx.com] **********************************************
  TASK [Gathering Facts] *********************************************************
  ok: [east01.xxxxx.com]
  TASK [test] ********************************************************************
  changed: [east01.xxxxx.com]
  PLAY RECAP *********************************************************************
  east01.xxxxx.com : ok=2    changed=1    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0 
  </code></pre>
  <p>and it looks like that is actually working (I can see the file on the target machine being modified when I run the playbook), but can someone tell me what is causing that WARNING:</p>
  <pre><code>[WARNING]: Invalid characters were found in group names but not replaced, use
  -vvvv to see details
  </code></pre>
  <p>??</p>
  <p>Also the warning says to &quot;use -vvvv&quot; and I was wondering where/how do I do that (since I am running this playbook under Tower)?</p>
  <p>Thanks!  Jim</p>
  <p>EDIT: I just did a test, where I ran the same yaml file using ansible-playbook (command line) and it ran without that warning, so I guess that the warning is something to do with some difference between ansible-playbook and Tower?</p>
