RESTIC_PASSWORD_COMMAND as env variable not being sourced?

[mattredact]

Hello! I am trying to source the Repo key passphrase through an env variable in .autorestic.env called AUTORESTIC_BACKBLAZE_RESTIC_PASSWORD_COMMAND

When I run autorestic check, the "key" in my .autorestic.yml gets populated with a random key instead of using the that I am trying to source by gopass.

The full env line looks like such

AUTORESTIC_BACKBLAZE_RESTIC_PASSWORD_COMMAND="gopass show -o restic-repo-password"

Is this supported for autorestic? Not sure why I can't get it to work. Any help would be much appreciated!!! :)

Cheers
