Dear,

i am using MM version 2.8.0 with the default calendar. Because the module is not able to get my caldav directly i download it via curl into a locally file and in the config of the calendar i am just pointing to the local caldav like this:

		{
			module: "calendar",
			header: "Chaoskalender",
			position: "top_left",
				config: {
					colored: false,
					coloredSymbolOnly: false,
				calendars: [
						{
					url: "http://127.0.0.1:8080/modules/calendars/chaos.ics",
					symbol: "calendar",
					
					}
			]
		}

	},

Works good so far BUT as soon as i create a series of events i get following error messages:

No toISOString function in curr.start 00)":20190909T164500
Whoops! There was an uncaught exception...
TypeError: event.start.getFullYear is not a function

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

In outlook, on the iphone or even in the groupware it is displayed perfectly without any issues.
So if anyone has an idea or solution to fix this issue i would be very glad in getting help here because i don´t have any ideas anymore.

Thanks in advance
