Automating Restic backups (feldspaten.org)

I'm having trouble automating the restic backup using systemd.

I followed the linked guide, which seems pretty straightforward. Backup works fine when I run it manually, but when I try to run systemctl status restic-backup.service I get the following error: Fatal: parsing repository location failed: s3: bucket name not found

I have triple-checked the file paths, and also added PassEnvironment=AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY RESTIC_REPOSITORY RESTIC_PASSWORD_FILE B2_ACCOUNT_ID B2_ACCOUNT_KEY to the restic-backup.service file, which I saw used elsewhere. This is my first time using systemd, so I'm not sure if I am overlooking an obvious step or what.

OS: Xubuntu

restic: installed locally following these steps

backup: Backblaze B2 bucket with s3

The problem seems to be that when you run restic with systemctl start, it passen on your user environment including the information of where your rclone.conf lies. When the systemd service runs on its own it doesn't have this. You need to either tell restic the path to your rclone config or set the home environment such that the systemd service checks the right location.
