I resolved by replacing this line

 

string cr_result = usd.createRequest(sessionID, userHandle, attrVal, prop, "", attr, ref requestHandle, ref requestNumber);

 

for this

string cr_result = usd.createRequest(sessionID, userHandle, attrVal, prop, "", new string[] { "id" }, ref requestHandle, ref requestNumber);
