Why do I get "cannot marshal None unless allow_none is enabled" error with MoveIt package?
I have generated a MoveIt config package for the Franka Panda robot using the MoveIt setup assistant. However, when trying to do
roslaunch panda_moveit_config demo.launch
I get the error
TypeError: cannot marshal None unless allow_none is enabled
and gives me a little further info:
load_parameters: unable to set parameters (last param was [/move_group/allow_trajectory_execution=True]): cannot marshal None unless allow_none is enabled
Why is this happening? I realize there are some related questions, e.g. this one, but I figure since it's generated from the MoveIt assistant there should be some more specific guidance.
