Custom ROS capabilities. InterfaceNameNotFoundException

edit

Hello!

I am trying to implement a system of custom ROS capabilities for my lab-specific turtlebot_bringup. I've got it to the point where the capability_server recognizes that the package has providers and interfaces; however, it appears that the server can't find any interfaces or the semantic interface at all. I've trying tinkering around with the syntax referencing the interfaces, but no dice.

Does anybody know more about ROS capabilities to help me figure this out?
