Calendar just loading

[Nik]

Hi guys,
my Magic Mirror wasn´t loading my Calendar, so I started investigating using npm start dev …
I got the Message down below. So I looked it up on the internet and found a modifier ical and node-ical file, which I uploaded… But is still not loading! I also changed back the time from 1970 to 1000 (/home/pi/MagicMirror/node_modules/rrule-alt/lib/rrule.js)…
Is there anything I can do?

Whoops! There was an uncaught exception…
TypeError: curr.start.toISOString is not a function

Are these the files you found and changed?

Exactly, but it still won´t work…
