server script customer search with filters not working

Hi,

I am conducting a simple customer search with filters and i get 'undefined' errors for nlobjError getCode(), getStackTrace() and e.getInternalId() 

logging the error i get:- 'Debug  system error  31/5/2007  11:53 PM  Gaurav Srivastava  undefined undefined undefined  Remove'

The search works fine without filter, however as soon as I include the filter, the script breaks.

I have conducted a saved search with the same filter and it works fine in NS however breaks in Server side user event script.

function code below.

try
    {
        var filters = new Array();
        filters[0] = new nlobjSearchFilter( 'internalid', null, 'anyOf', '622', null  );
        var results = new Array();
