Need help debugging a script for attribute customizations

Hello RTC scripting guru's,

Below is a script that I am using to try a change the value of "status_action_item" based on whether the "assigned_date" is past "test_date_1", if the "assigned_date" is before the test_date_1, set the "status_action_item" to "Open", if not set the value to "Overdue".  Currently, it seems to get hung up before even reaching the if-else statement, the only value that shows up is the default value set in the enum definition for "status_action_item".  I am invoking this script from the "Calculated Values" section in the process configuration.

RTC 4.0.0

Thank you in advance,
Brad Ebert

(function() {
var WorkItemAttributes= com.ibm.team.workitem.api.common.WorkItemAttributes;

dojo.declare("org.example.workitems.providers.status_action_item", null, {

    getValue: function(attributeId, workItem, configuration) {

        // Get the assigned date and the due date and compute the difference in days.
        
        var assignedDate= dojo.date.stamp.fromISOString(workItem.getValue(WorkItemAttributes.assigned_date));
        var dueDate= dojo.date.stamp.fromISOString(workItem.getValue(WorkItemAttributes.test_date_1));
        var dayDiff= dojo.date.difference(assignedDate, dueDate, "day");
       
        // Return a string that indicates whether the work item is open or overdue
          
              if (dayDiff < 0)  return "Open";
                 else return "Overdue";
