<![CDATA[MagicMirror won't load.]]>I tried to upgrade MagicMirror earlier but then MagicMirror would not load. No black screen, just never opening. So I did a fresh install of Raspberry Pi OS and Magic Mirror.
I am using a Raspberry Pi 4 with Raspberry Pi OS 64-bit. Everything was working so I went ahead and installed some modules and copied over my config and CSS files. Now it won’t load again. I have tried using pm2 start mm.sh (I set up the mm.sh as per the MM documentation). I have also tried pm2 start mm.sh. Terminal gives my no errors, it looks like MM is loading, but MagicMirror doesn’t load.

My pm2 mm-error log file has this message:

If I run pm2 info mm I get this info

 Add your own code metrics: http://bit.ly/code-metrics
 Use `pm2 logs mm [--lines 1000]` to display logs
 Use `pm2 env 0` to display environment variables
 Use `pm2 monit` to monitor CPU and Memory usage mm

I am not sure what to do to fix this. I have been trying to figure it out for over 6 hours and have no answers. Any help is appreciated.

Require stack:

  • /home/pi/MagicMirror/modules/MMM-OneTracker/node_helper.js

in the MMM-OneTracker folder do

npm install node-fetch@2

we removed that library in this release as node has a built-in and supported fetch
