I upgraded from 2.22 using the sdetweil script, and it went through it without errors.

If I ask pm2 MagicMirror is online.
The log file looks like this:

pi@bathmirror:~/MagicMirror $ pm2 logs MagicMirror
[TAILING] Tailing last 15 lines for [MagicMirror] process (change the value with --lines option)

I don’t think it’s the ‘request’ thing, I did the search for request, and commented out all the modules that used that.

The config looks like this:

let config = {
