Forman - Ansible - No executor available

Hi All,

I just tryout foreman with ansible plugin. When I try to run ansible from
the foreman webui I find following in my log files:

App 15358 stderr: E, [2016-10-31T20:19:47.474931 #15817] ERROR –
/client-dispatcher: No executor available (Dynflow::Error)
App 15358 stderr:

handle_envelope' App 15358 stderr: /opt/theforeman/tfm/root/usr/share/gems/gems/dynflow-0.8.15/lib/dynflow/actor.rb:6:inon_message'

Any idea what is missing?

thank
