@neoplex unfortunately, cannot reproduce. If it's easy to see this, can you please send a mail to support@cloudron.io and we can take a look to debug this further.
This is basically a static web frontend with a simple cron based backend. Hasn't seen any breaking updates in a decade and there are existing docker images for it. No one else interested?
I've looked through the app development guide and trying to find some time to build some images for cloudron.
