What is the workaroud for thisMap.addInclude when using in scoped applications?

[surya76]

the following script works in globla application

when iam trying the same in our one of the scoped application iam receiving the below error

ERROR:   Function addInclude is not allowed in scope (my scope name)

var session = gs.getSession();
var timeZone = session.getTimeZoneName();
var scheduleGUID = 'caa944c2db7a3b40746bc4048a9619ff'; //one specific maintenance schedule
var daysAhead = 21;
gs.log('Session timezone is: ' + timeZone);


var schedule = new GlideSchedule(scheduleGUID);
schedule.setTimeZone(timeZone);

gs.log('Schedule is: ' + schedule.name.toString());

// Start from Today

var gd = new GlideDate();
var gdt = new GlideDateTime();

gdt.setNumericValue(gd.getNumericValue());

// GDT (GlideDateTime)
// Start Date
var sd = new GlideDateTime();
sd.setValue(gdt.getDate() + " 00:00:00");

// End Date
var ed = new GlideDateTime();
ed.setValue(gdt.getDate() + " 23:59:59");
ed.addDaysUTC(daysAhead);

// SDT (GlideScheduleDateTime)
// Start Date
var ssd =   new GlideScheduleDateTime(sd); // Start Day
ssd.setTimeZone(timeZone);

// End Date
var sed =   new GlideScheduleDateTime(ed); // End Day
sed.setTimeZone(timeZone);

// Get Where Schedule Entries overlap with your Start/End Dates    
var scheduleMap = schedule.getTimeMap(sd, ed, timeZone);
var span = new GlideScheduleDateTimeSpan(ssd, sed);
var thisMap = new GlideScheduleTimeMap();

thisMap.addInclude(span);
thisMap.buildMap(timeZone);
overlaps = scheduleMap.overlapsWith(thisMap, timeZone);
overlaps.buildMap(timeZone);

gs.log('Getting spans from now and the next ' + daysAhead + ' days.');
while (overlaps.hasNext()) {
      var overlapSpan = overlaps.next();
      gs.log("Dates:   " + overlapSpan.getStart() + " - " + overlapSpan.getEnd());
}
