Failed to get sensor modes (error 64) with imx219

hello,
i have a problem, when i want to use my imx219 camera on the apps/samples/argus_camera
i have this message :

021-04-01 17:24:14.248 ERROR external/com_nvidia_isaac_engine/engine/alice/components/Codelet.cpp@229: Component ‘argus/camera’ of type ‘isaac::ArgusCsiCamera’ reported FAILURE:

Failed to get sensor modes (error 64)

2021-04-01 17:24:14.248 ERROR external/com_nvidia_isaac_engine/engine/alice/backend/event_manager.cpp@43: Stopping node ‘argus’ because it reached status ‘FAILURE’

i don’t know why i have this message because i can access to the camera with nvarguscamerasrc on opencv i have tried a lot more application, and it works fine i don’t know why the isaac sdk cannot find my cam

$ dmesg | grep imx219
