ansible-plugin: Rundeck does not understand the host defined in ansible inventory

Hi guys, Can you guys help me how to get rundeck to work with ansible ?

I have success added nodes to rundeck using ansible inventory file, but the job I created running a simple ping module (job with Ansible module), I only got this warning:

[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: Could not match supplied host pattern, ignoring: all
[WARNING]: provided hosts list is empty, only localhost is available
[WARNING]: Could not match supplied host pattern, ignoring: aavn-laptop25
[WARNING]: No hosts matched, nothing to do

As you can see rundeck knows my node (aavn-latop25) but ignore it.
