Incorrectly parsing .filebrowser.json when password is provided

[rgryta]

Description
While trying to automate homelab deployment, I've encountered a problem when trying to set up default credentials for admin user.
I'm utilizing docker config functionality to modify the .filebrowser.json file with properly set up credentials.

This however leads to some corruption to the overall configuration and based on a docker image that I've built myself (although just the backend part of it) it looks like dollar signs are the issue.

Link to a gist with docker-compose that I've been using to debug this issue: https://gist.github.com/rgryta/82a74ae2374da8ae1359c8c04af38581

Expected behaviour
Logging in as admin with password admin should work.

What is happening instead?
Incorrect credentials error (and when adding some print statement to the code, it seemed like it would crash somewhere here (then again, I have no idea if my local docker build was correct - issue exists with the official docker image though):

Additional context
N/A

How to reproduce?
docker-compose up -d on the provided gist example and try to log in as admin:admin.

I think password is not supported in the json config, there's no definition in the source code storage/bolt/importer/conf.go, see oldConf struct.
