module installation confusion - Improve error handling

I'm dabbling with the module system, but am stuck getting modules installed. I've cloned the repository, and run install.sh to install the allsky_dewheater module. It shows up in /opt/allsky/modules.

I don't see it in the Module Manager, however. Nothing in /var/log/allsky.log.

I also zipped up the directory and tried using the Upload facility within the Module Manager, but got Failed to upload the plugin. Unable to move the file.

Version: v2023.05.01_04 on a RPi4 with 4GB RAM.

Never mind, it looks like my problems were because of some earlier efforts. I had copied a prototype module directly into scripts/modules, and it was generating an error in /var/log/allskyperiodic.log. I stopped allsky, deleted the offending module from config/modules/postprocessing_periodic.json, and now the Module Manager is showing the modules installed by install.sh.

Leaving this here for others. I could write up some extra troubleshooting detail for the module installation step?
