MMM-MyCalendar stopped working on MagicMirror 2.25
-
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:

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

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 -
“My mirror is up now, but the calendar is just stuck loading.”

How do I get it done? -
@svoe88 you missed one of the changes in the workaround. the author needs to fix their module.
