Suitelet List - Unexpected Error

Hi All,

has anyone received this error when executing a suitelet list?

UNEXPECTED_ERROR Ticket: flhz2o8z1vpggpwvpo09f

I did read in another thread about this error but that was due to the nlobjSearchFilter api not containing an internal ID.

             var returncols = new Array();                    returncols[0] = new nlobjSearchColumn('internalid');                   returncols[1] = new nlobjSearchColumn('companyname');                   returncols[2] = new nlobjSearchColumn('zipcode');                   returncols[3] = new nlobjSearchColumn('salesrep');              //returncols[4] = new nlobjSearchColumn('deptbought');                          var myresults = nlapiSearchRecord('customer', null, new nlobjSearchFilter('zipcode',null,'contains','cw4'), returncols);                 list.addRows( myresults );
