Archive Saved Posts Without Folders

[BDFR-Assistance]

I'm not sure why I get this error, especially since in the sample usage, --folder-scheme is used.

How can I make my command above correct? I want to archive all my saved posts without them being placed into folders of their respective subreddits? Thank you!

Edit: Is it possible that the sample usage is incorrect? Because --folder-scheme is an option only available to the download command, apparently.
