Cross posting from the isaac_ros_nitros issues board.
I am trying to implement a version of custom_nitros_pointcloud, following the other examples found in the isaac_ros_managed_nitros_examples. However, i am getting a nasty error when doing so of:
Starting >>> custom_nitros_pointcloud
--- stderr: custom_nitros_pointcloud
