Recently, my sync is generating a notification for a new event every time it runs. The details of the reported event are in the text from the notification as below.

GAS-ICS-Sync made the following changes to your calendar:

Work: 1 added events

Name: undefined
Start: 2025-01-24 at 13:00 (UTC-05:00)
End: 2025-01-24 at 13:00 (UTC-05:00)

There is no event on the source calendar (Work) at the time specified so nothing for me to delete there. There was never an event scheduled on the 24th at 13:00. No event was created by the sync on the target calendar. But I keep getting the notification that a new event was added during the sync.

I have tried uninstalling and re-installing the script to no avail.

Is there a way to reset something (history?) so that this event is no longer detected.

I was unable to find the ghost event. I use Thunderbird and it did not appear there in any view. I never intentionally scheduled anything on that date or time. The only clue I had was that I had someone else schedule a meeting and then cancel it for 13:00 - 13:30. Maybe the cancellation did not clear.

SOLUTION: I set the GAS-ICS-Sync onlyFutureEvents=true and removePastEventsFromCalendar=true. This deleted all past events from the target (ghost or otherwise) and the issue is resolved. It also made me realize that in this case, I didn't really need to maintain a history of events on the target calendar. That is, I do want to know when a work meeting is coming up on my personal calendar but…

That is, I do want to know when a work meeting is coming up on my personal calendar but once the meeting is done, I don't need it on my personal calendar especially as my meeting history is maintained on my work calendar.

So, for me problem solved.

Could you open your source *.ics in a text editor and see if you can find the definition of said event?
Searching for the startdate 20250124 should work.

I have opened the last ics file I have for this event which was the cancellation notice. Am I looking for something?

Can you please share the definition (BEGIN:VEVENT to END:VEVENT).

Sure. Below is the most recent ics associated with the event. It is an event cancellation. I have replaced personal information with "xxxx".
