Hikvision C# sdk NET_DVR_SET_CARD ERROR 9 CARD AND MEMBER ENROLMENT ERROR

Question

I am building a fingerprint enrollement system with the help of the Hikvision SDK I downloaded from their website and the language I am using is C#. From the sample of the code section for the card enrolment I tried the login and the device is logging in and when I try to add the member with card meaning set to device it gives the error NET_DVR_SET_CARD ERROR 9.

I'll attach the screenshot of the UI and the form code and I'll also attach the zip file containing all the example in sdk.
