@piketfencecartel I just tried your config on both MM 2.1.3 and 2.5.0 (the latest build) and MMM-MyScoreboard started without issue.
Dumb question, I know, but did you remember to run
npm installl in the
MMM-MyScoreboard directory? If you haven’t done that, run that command and then restart MM to see if it fixes your issue.
