Current Behavior

The container fails to run, and exits with several sed: can't read /etc/openvpn/mullvad/default.ovpn: No such file or directory errors.

Expected Behavior

Container was working with above docker-compose file, using image tagged :4.0. It stopped working after a recent pull.

How have you tried to solve the problem?

Switched from :4.0 tag to :latest and a few different point releases up to :4.3.2.
Checked that my OS (Ubuntu jammy) was up to date; rebooted.
Tried recreating the container, with same effects
