Have a check if below command can get image.

gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! 'video/x-raw(memory:NVMM),width=1920,height=1080' ! nvvidconv ! xvimagesink sync=false 

gst-launch-1.0 nvarguscamerasrc sensor-id=1 ! 'video/x-raw(memory:NVMM),width=1920,height=1080' ! nvvidconv ! xvimagesink sync=false

those commands can get image
