No default projection is set

edit

I am trying to benchmark with SBL planner and I am getting the following error.

 [ERROR] [1543886618.510289253]: No default projection is set. Perhaps setup() needs to be called
[ERROR] [1543886618.510893246]: OMPL encountered an error: No projection evaluator specified
[ERROR] [1543886618.685283]: Mongo process exited with error code 100

and my .yaml file reads as,
