Answer 1

Mostly this issue is encountered when start > end

Example: You're specifying Start and End Date as follows:

• Start: 2020-10-10T13:30:00+5:30 (i.e. 10th Oct 2020 @1:30PM)
• End: 2020-10-10T13:00:00+5:30 (i.e. 10th Oct 2020 @1:00PM)

End Time Should be Greater than the start Time.

{
    "summary": "some summary",
    "description": "some description",
    "location": "some location",
    "end":  {"dateTime" : "2020-10-10T13:30:00+5:30"},
    "start" : { "dateTime" : "2020-10-10T13:00:00+5:30"},
}
