It was in the previous post, about 2/3 of the way down, just below the obnoxiously large text.

yes you have to use force instead of apply

@sdetweil

Force update complete. MM still not working properly, but it’s something different, which I’ll call progress.

[ERROR] (node:2061) UnhandledPromiseRejectionWarning: Error: Cannot find module ‘fetch’
(Full text below)

I see some answers for ‘node-fetch’ in topic #18055, but I’m not sure if that fix will work on this problem. I’m still digging around, but not seeing this exact problem so far. Thanks.

yes we removed some libs as fetch is built-in in node 18 up.

that module has a fix

go to the MMM-Wallpaper folder (check spelling)
git pull
to update

then restart mm

@sdetweil
We’re up and running! Thank you so much for your patience. I have learned a lot from this go round and I’m hoping that the next update will go much smoother. I still don’t fully understand how to check the test run for compatibility with my configuration before applying the changes, but I have a little time to get smarter before the next update. Have a great rest of your week.

[sdetweil]

@rmcon great that you got it working

on the test run, mostly currently it’s looking for mm files you might have changed for some reason, and conflict w the new release.

most of the other issues I handle, upgrade node, npm and pm2 if needed.

and in this release on pi0, increase swap space and increase the node heap space.
