@CarolMa6 Use below scripts. Don't use getDisplayValue() for date type of field. It is giving undefined value . I tried below script in PDI and it worked.

var date = fd_data._1__get_catalog_variables.termination_date;
var gdt = new GlideDateTime(date + " 00:00:00");
gdt.addSeconds(54000);
return gdt;
