Calendar module not showing events (fetch error)

[nakulbende]

Using the default calendar module to display events - the same config worked for a while. I updated MM, and this does not work anymore. Getting the following issue regardless of which link I have in config - I checked and the cal links are working.

I am using a RPi, MM is up to date. Thanks for all the help community!

Here is my config for this module:

// Calendar
 			{
 				module: "calendar",
 				//header: "Calenar",
 				position: "top_right",
 				config: {
 					colored: true,
 					maximumNumberOfDays: 60,
 					maximumEntries: 12,
 					displaySymbol: true,
 					timeFormat: "absolute",
 					broadcastPastEvents: true, 
 					showEnd: false,
 					wrapEvents: false,
 					calendars: [
 						{
	 						//symbol: "fas fa-glass",
	 						//maximumEntries: 4,
	 						url: 'https://calendar.google.com/calendar/ical/en.indian%23holiday%40group.v.calendar.google.com/public/basic.ics',
	 						//color: "#c97dff" // #ff8989, #ffc386, #f9ff99 is red, orange and yellow
	 					},
	 					{
	 						symbol: "fas fa-heart",
	 						maximumEntries: 4,
	 						color: "#a1ffb6",
	 						url: "XXX",
	 					},

	 					},
 					],
 				},
 			},

@nakulbende Looks like you might have missed a step in installing your mirror from my point of view. the module “fetch” is missing, which indicates “npm install” may not have been run from the MagicMirror directory. How did you install?

It could also be that node is too old. Check whether you have node 18 or newer with: node -v
