I have a simple Python application that serves a WebSocket. I succeeded in snapping the application and running it on Ubuntu 18.04.5 LTS. I'm also able to install the snap on virtual ctrlX CORE (1.4.1).
However, when I try to run my snap (server-alt) on virtual ctrlX CORE I get the permission denial shown below:
How do I point my snap to the writable snap folder (presumably this is /writable/system-data/snap/server-alt), as opposed to the default (and in our case non-existent) snap path: /home/$USER/snap/server-alt?
Complete project together with sample html is attached.
