Error when importing an event with no End Date/Time

[eiclu]

Hi, the tool I am importing from allows creation of events without an end date. When trying to import such an event via wp-event-aggregator, the tool throws a fatal exception.

Example Event where the error occurs:

BEGIN:VCALENDAR
CALSCALE:GREGORIAN
VERSION:2.0
PRODID:-//Elixir ICalendar//Elixir ICalendar//EN
BEGIN:VEVENT
CATEGORIES:Category
DESCRIPTION:Description
DTSTAMP:20241013T164241Z
DTSTART;TZID=Europe/Vienna:20241025T190000

SUMMARY:Test Event
UID:00000000-0000-0000-0000-000000000000
END:VEVENT
END:VCALENDAR

Fixed event without an error:

BEGIN:VCALENDAR

BEGIN:VEVENT

DESCRIPTION:Description
