Did you ever arrive at a solution for this issue? Running into the same error on my container.

Its due to the container hardcoding the user ID and group ID, so your environment settings for PUID and PGID aren't being applied, and the UID 1000 / GID 1000 permissions aren't allowing the config file to be created/read on the bind mount.
You could set /opt/seedsync/data to be owned by 1000:1000 (and if needed add the group to your user to manage or adjust permissions)
Seems relatively useful to implement that environment support but I'm not sure if the project is active.
