Google Apps Script to remove hangouts links from calendar events - google-apps-script

Question

I have successfully accessed a Google calendar event and can change the color, but I'm stuck when it comes to removing the hangouts link.
I'm attempting to use code to automatically remove the hangouts links when I am the meeting originator and have not changed the hangout name, but I'm not having any success in actually changing the link.
Any help greatly appreciated.
function removehangout() {
var calendarId = 'primary';
//var calendars = CalendarApp.getOwnedCalendarsByName('Mirage ELDRIDGE');
var now = new Date();
// Determines how many events are happening in the next 24 hours x 1 days.
var now = new Date();
var endr = new Date(now.getTime() + (1 * 24 * 60 * 60 * 1000));
var events2 = CalendarApp.getDefaultCalendar().getEvents(now, endr);
Logger.log('Number of events: ' + events2.length);
var events = Calendar.Events.list(calendarId, {
timeMin: now.toISOString(),
singleEvents: true,
orderBy: 'startTime',
maxResults: 5
});
if (events.items && events.items.length > 0) {
for (var i = 0; i < events.items.length; i++) {
var event1 = events.items[i];
var d = event1.description;
var ttitle = event1.summary;
var whoby = event1.creator.email;
Logger.log(ttitle + ' by: ' + whoby);
if(whoby.indexOf('mirage.eldridge') != -1){
Logger.log(ttitle + '--> was by mirage');
var hangoutname = event1.hangoutLink;
Logger.log(ttitle + '--> hangout link name --> ' + hangoutname);
if (hangoutname != null) {
if (hangoutname.indexOf('mirage-eldridge') != -1){
//delete this link here
Logger.log(ttitle + '--> remove hangout');
//event.setHangoutLink(null);
//var idno = event.iCalUID
//CalendarApp.getEventSeriesById(idno)
event1.HangoutLink = null;
Logger.log(ttitle + '... ' + event1.hangoutLink);
Logger.log(event1.iCalUID);
//event.setcolorId('11');
var event2 = Calendar.Events.get(calendarId, event1.id)
event2.colorId = 9;
event2.hangoutLink = 'fred';
//Calendar.Events.patch(event2,calendarId,event1.id);
Calendar.Events.update(event2,calendarId,event1.id);
}
} else {
Logger.log(ttitle + ' -- do not remove ' + hangoutname);
}
}
if (!d)
d = '';
//var foundlinkyes = d.indexOf('HangoutLink');
//var actuallink = event.hangoutLink;
//var hasrlink = 'True';
//if (!actuallink) {
//Logger.log(ttitle + ' no link found');
//hasrlink = "False";
//}
//Logger.log('desc: ' + ttitle + '-- foundyes: ' + foundlinkyes);
//if (foundlinkyes == -1 && hasrlink == 'True'){
//if (event.hangoutLink && (d.indexOf('Hangout: ')== -1)){
//Logger.log (event.summary + ' - ' + event.hangoutLink + ' - ' + event.description);
//Logger.log(ttitle + ' added this ' + event.hangoutLink);
//event.description = 'HangoutLink: ' + event.hangoutLink + '\n\n' + d;
//Calendar.Events.update(event, calendarId, event.id);
//foundlinkyes = 0;
//hasrlink = 'True';
//}
//}
}
} else {
Logger.log('No events found.');
