Could not insert event with Bad request

[dmytr0]

I want to create Event in calendar with such code

         Event event = new Event()
                .setSummary("Vacation from app")
                .setLocation("800 Howard St., San Francisco, CA 94103")
                .setDescription("A chance to hear more about Google's developer products.");

    DateTime startDateTime =  new DateTime("2020-11-10T00:20:50.52Z");;
    EventDateTime start = new EventDateTime()
            .setDate(startDateTime)
            .setTimeZone("Europe/Kiev");
    event.setStart(start);
    DateTime endDateTime = new DateTime("2020-11-10T23:20:50.52Z");
    EventDateTime end = new EventDateTime()
            .setDate(endDateTime)
            .setTimeZone("Europe/Kiev");
    event.setEndTimeUnspecified(true);
    event.setEnd(end);
    googleCalendar.events()
            .insert(calendarId, event)
            .execute();`

But receive a response

{ "code" : 400, "errors" : [ { "domain" : "global", "message" : "Bad Request", "reason" : "badRequest" } ], "message" : "Bad Request" }

From this message I really do not understand which data is bad...

great support.

3 years later and I'm facing the same error.

@dmytr0 I'm guessing you haven't found the reason for it
