NC 21/Apache Docker- Permissions Nightmare Running Custom Script(s)

Hi !

I have NC 21/Apache from Docker hub (on Debian Buster host), and run into problem executing custom Shell & Python scripts. In short - even anything from /usr/bin (e.g. /usr/bin/Python3) can’t be executed as www-data user. I logged into NC21 Docker container, added “www-data” to the “users” group, nothing changed. Another option is to add “www-data” to the sudoers, yet its really awkward.

Anyone know how to fix this problem?
Thanks in advance.
