Trouble Getting CSI Camera to connect

When I hook up my CSI camera and run from I get the following error:

Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:521 No cameras avaiable

Any ideas? I get this error with multiple cameras and have found no succesful way to connect to the CSI cameras.

Is your camera from our camera partners? The camera partners shall offer the driver and device tree. If it is your own camera, you need to follow [Sensor Driver Programming Guide] to bring the camera up.

Is there a list of camera partners somewhere? I’ve tried a few different ones including Dorhea RP 3 model b+ camera webcam 22 FoV OV5647.
