Does not load planning adapter plugin

edit

Hello,

I'm trying to write my own planning adapter plugin based on the Tutorial: http://wiki.ros.org/industrial_trajec...

The build does not throw any errors but during the start of the launch file I get the following error:

[ERROR] [1618479719.360767428]: Exception while loading planning adapter plugin 'safety_planning_request_adapters/AddSafety': According to the loaded plugin descriptions the class safety_planning_request_adapters/AddSafety with base class type planning_request_adapter::PlanningRequestAdapter does not exist.

I don't know what step I have missed or which line might be wrong. Any tips would be appreciated.
