Getting error while invoking data validation manager BS from Script in Application Pre_navigate

Hi,

I'm receiving error while invoking 'Data Validation Manager' in application pre_navigate script in OUI.  Can you please help.

"Unable to Load Message 0xffff(sbl-gen-00000)"

if((DestViewName != "<My View name >") && (DestViewName != ""<My View  Name_1 >") && sOpenUI != "1") // Loop for HI

{

TheApplication().RaiseErrorText("Please associate a Contact or to specify Unidentified Contact.");

}

if((DestViewName != "<My View name >") && (DestViewName != "<My View  Name_1 >") && sOpenUI == "1")// Loop for OUI

{

TheApplication().SetProfileAttr("CCBTestJVVal","Y");

var sRuleSetName = "Test Rule Set Validation";

var oBS = TheApplication().GetService("Data Validation Manager");

var psInput = TheApplication().NewPropertySet();

var psOutput = TheApplication().NewPropertySet();

psInput.SetProperty("Rule Set Name", sRuleSetName);

psInput.SetProperty("BusObj", "Account");

psInput.SetProperty("BusComp", "Contact Log");
