Hello, I am trying to get this to work with Ubuntu 18.04 on a Jetson Nano Dev kit with Ros melodic. I have started with a clean install 3 times and still have an issue with running: $ roslaunch jetson_csi_cam jetson_csi_cam.launch sensor_id:=0 width:=1280 height:=720 fps:=24 I constantly get the following error: [ERROR] [1648831545.254730904]: Could not get gstreamer sample

Do you have any guidance on why this may be an issue or how to troubleshoot this? Nothing I try seems to work.
