@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;

@CarolMa6

the error clearly is because of that script.

Is that variable as standalone and not part of MRVS?

If yes then Did you check if variable name is correct?

that variable is of type Date or Date/Time?

Did you add logs and see what came in date variable?

If my response helped please mark it correct and close the thread so that it benefits future readers.

Hi,

Probably you need to make sure that the "date" variable in the first line contains some data, before you try to add/convert the date to a datetime.

Something like below might help (somewhat simplified example).

var date = fd_data.trigger......getDisplayValue();
var gdt;

if (!date){
  // some action to take if the value does not exist
  gdt = new GlideDateTime();
  ....
}
else{
  gdt = new GlideDateTime(date + ...);
  gdt.addSeconds(...);
}

return gdt.getValue();
