Google Calendar Event ID Mismatch

What are you trying to achieve?

I’m trying to sync Notion tasks as events over to Google Calendar. The initial creation of Event in Google Calendar works just fine but I noticed that the Event ID updated within Notion is different from the URL section from Google Calendar. This is evident from the 404 error I faced when trying to update the task from Notion over to Google Calendar. How to check or ensure that the Event ID is correct?
