I want to write my own plugin for Volumio 2 but I am struggling since my plugin crashs the web UI. After installing it and calling the configuration page I only see the loading indicator. After refreshing the page in my browser it is not reachable anymore. Any SSH connection is still usable. So I have tried to restart the mpd daemon but without success. The system log has no entries either.
I use the Spotify plugin as template.
Are there any instruction how I can setup an development environment?
