Error on agora1 deploy TASK [AgoraElections, activator clean & stage]

[nfortea]

When I execute
time sudo ansible-playbook -i inventory playbook.yml -vvv
I receive a incomprehesible error on TASK [AgoraElections, activator clean & stage].
I try to execute manually /home/agoraelections/activator-1.2.12-minimal/activator clean;
This is message I obtain with user agoraelections:

Unable to open the docs in your web browser.  To open them manually navigate to:
http://typesafe.com/activator/docs
 Did not detect an activator project in this directory.

How I can avoid this error? I tried to create a new project but I don't know project-name and template to use.
I need any help, please.

Deactivating line - include: app.yml
in agora-elections/main.yml, I can continue with deploy process but I'm sure i have another trouble in future
