Get a New Event Summary and Description - google-apps-script

Question

Trying to find a way to get the Summary and Description of a new Event.
I can get the attendees, conference data and event id that will be persisted when event is saved, but no reference to Summary or Description.
Example payload passed to the 'eventOpenTrigger' and 'eventUpdateTrigger':
{
"commonEventObject": {
"platform": "WEB",
"hostApp": "CALENDAR"
},
"calendar": {
"conferenceData": {
"conferenceSolution": {
"key": {},
"iconUri": "https://lh3.googleusercontent.com/...",
"name": "Test"
},
"notes": "test",
"parameters": {
"addOnParameters": {}
},
"conferenceId": "test",
"entryPoints": [
{
"uri": "https://test",
"entryPointType": "video",
"label": "test"
}
]
},
"id": "EVENT_ID",
"calendarId": "email#company.com",
"organizer": {
"email": "email#company.com"
},
"capabilities": {
"canSeeAttendees": true,
"canSetConferenceData": true,
"canAddAttendees": true,
"canSeeConferenceData": true
},
"attendees": [
{
"email": "email#company.com",
"self": true,
"displayName": "email#company.com",
"organizer": true
}
]
},
"hostApp": "calendar",
"clientPlatform": "web"
}
When try to use Calendar.Events.get(calendarId, eventId) to get more event details, it returns 404, which makes sense since the Event is not yet persisted. Just would be nice to be able to get the event Summary and Description at the time a user creates an event rather than having to have them reopen it again afterwards

Answer 1

It's intended behavior that the calendar event object does not return you the event summary and description, see also here
However, if you are able to trigger the eventOpenTrigger, you should also be able to use the method Events: get with the eventid the event object returns you.
Make sure you specify the calendar id and event id for the requets correctly. You can also test with the Try this API first before implementing the request into your code.
Since 'eventOpenTrigger' and 'eventUpdateTrigger' fire when an (already saved event) is being clicked on or when the Save button is clicked when a user modifies an event - there should not be any issues with the event not being saved yet.
The Calendar API documentation specifies that a 404 error is means:
The specified resource was not found. This can happen in several
cases. Here are some examples:
when the requested resource (with the provided ID) has never existed
when accessing a calendar that the user can not access
So most likely you are providing the wrong calendar or event id.
