Docker run config used

mounted vars

Current Behavior

Been using for several years and working fine. Every now and then I need to update the node when my provider changes names of them.

I've mounted my opvn file but transmission can't find it then goes to the repo to find a config and breaks and shuts down: ./etc/openvpn/fetch-external-configs.sh: line 18: config_repo_temp_dir: unbound variable

Expected Behavior

transmission finds the default.opvn config and uses it instead of going to the repo

How have you tried to solve the problem?

I updated to most recent release and that didn't help
I tried several nodes from my provider to ensure that isn't the case
I found that the repo for my provider (PROTONVPN) was changed last month and broke the nodes I was using and I was to use my own .opvn so this doesn't randomly happen again in the future
Downloaded .opvn configuration, commented out two lines (specific to my provider):
```
#up /etc/openvpn/update-resolv-conf
#down /etc/openvpn/update-resolv-conf
```
Mounted the new opvn file to /etc/openvpn/protonvpn/default.opvn
Changed the environment variable to default instead of the node to use local config
Looked in the docs for using local opvn file and proper way to point to it but didn't find anything. (I don't want to push to the repo since it can get changed and break my config again).
Tried using 'custom' as vpn provider but that didn't fix the issue, still crashes
