ROS Launch dies immediately

[ariel-elbit]

Hi, After setting up the bezier-exmples project as mentioned on the ReadMe, When I launch anyone of the examples the process dies immediately. What happens is that the rviz loads, I see the robot and the object loaded into the world. But right after that the entire process dies. When I do see the object for just a moment before the process dies, there is no path on it.
I would love some help,
Thanks a lot,
Ariel
