I figured it out. I use the free plan, so I cannot use API version 3.0. I have to use API version 2.5. Furthermore I have to use the /weather endpoint.

I got it working again by adding these 2 settings:

apiVersion: '2.5'
weatherEndpoint: "/weather"

@sdetweil yes, still happening.
just noticed this second page, trouble shooting now. I get a 401 unauthorized error.

I have the same issue. These are my settings:

  module: "weather",
  position: "top_right",
  config: {
    lat: "52.262524",
    lon: "6.797571",        
    apiKey: "****",
    appendLocationNameToHeader: false,
    type: "current",
    degreeLabel: true,
    decimalSymbol: ",",
    showWindDirection: false,
    showFeelsLike: false

I’ve copied all options and the calendar still works. Problem solved, but no clue what the problem was…

I’d like to thank everyone eho helped me figuring this out.

I’ve done some more testing and I figured out that must be some option in my config.js that causes my problem.
My calendar works when I load the config.js.sample and paste the url of my calendar in it.

Guess I’ll have to do troubleshooting to do…

(no worries about the calender link, I will change it after I’m done testing. It has some bogus appointments in it.)

{
module: "calendar",
header: "Agenda",
position: "top_left",
config: {
	broadcastEvents: false,
	calendars: [{
		url: "https://calendar.google.com/calendar/ical/gjv.de.groot%40gmail.com/private-5652f141b7d1dbb385f50a786a34827a/basic.ics"
	}],
	dateFormat: "D MMMM YYYY",
	fade: false,
	getRelative: 0,
	hidePrivate: true,
	maximumEntries: 8,
	maximumNumberOfDays: 7,
	maxTitleLength: 50,
	showEnd: true,
	showLocation: true,
	timeFormat: "absolute",
	urgency: 1,
	useRelativeDates: false
}

I cleared my entire calendar to be certain there were no appointments that would cause the problem, problem still occurs.
I can download basic.ics without a problem.

@Omeliel I gave it a try. Didn’t work.

@sdetweil These are not the only two appointments in the calendar. I only showed two appointments, so you get an idea what it looks like. And even if they were the only two and in the past, then I would get something like: “no future appointments” on my main screen.

I forgot to mention that “node debug.js” gets stuck as well. I don’t get a prompt after the line.

I recently updated my MagicMirror. Since then my calendar isn’t working anymore.
I don’t see any errors when I try pm2 logs mm.
When I try node debug.js it stops after showing some appointments and a line.

I also tried a complete a reinstall, same effect.

I’m using a Raspberry Pi 3 A+.

When I set maximumEntries: 8 I only see items 3 items.
I did some testing and I think the reason I only see 3 items is because some items are excluded.
I think the excluded items are counted as well.
