MMM-MyCalendar stopped working on MagicMirror 2.25

svoe88 · Oct 26, 2023, 8:39 PM

Hello, everyone,

I’ve encountered an issue with my MagicMirror setup and need help resolving it. I hope someone here can provide me with some advice or solutions.

Problem Description:

I’ve updated my MagicMirror software to version 2.25.0, and after the update, I’m receiving the following error when I attempt to start MagicMirror:

magic@magic:~/MagicMirror $ npm start

It appears that the error is related to the MMM-MyCalendar module

Can anyone guide me on how to fix the error and get my MagicMirror working correctly again?

It works now

For others it doesn’t work too then I copy this code into calendarutils.js

@svoe88 for MyCalendar

always look to the module github first

see https://github.com/jclarke0000/MMM-MyCalendar/issues/40

config template file not exists, no envsubst

this is a new optional feature where you can have a file of properties
and apply them to the config.js, not having them hard coded

But I’m still new to getting it all up and running

@svoe88 said in config template file not exists:

ReferenceError: fetcher is not defined
at fetchCalendar (/home/magic/MagicMirror/modules/MMM-MyCalendar/

didn’t do the patch right

karsten13 · Oct 26, 2023, 11:06 PM

title of this thread has nothing to do with the problem

sdetweil · Oct 26, 2023, 11:12 PM

@karsten13 I fixed the title

svoe88 · Oct 27, 2023, 4:21 AM

@sdetweil
How do I get it done?

sdetweil · Oct 27, 2023, 1:21 PM

@svoe88 you missed one of the changes in the workaround. the author needs to fix their module.

svoe88 · Oct 27, 2023, 1:21 PM

@sdetweil
It works now

For others it doesn’t work too then I copy this code into calendarutils.js
