    Hi [mention:f0bd4e317b8142ee905bd53aa9bb8837:e9ed411860ed4f2ba0265705b8793d05]

    The reason for error would be that pv!Vehicle is null so it is not able to get the fields vehicleyear or vehiclemake  or vehiclemodel .

    Can you check if PV Vehicle has data.

    Also as a best practice, it is recommended to access values from CDT in null safe manner using index or property functions for example in your case you can access as index(pv!Vehicle, "vehicleyear", null)
