I've written an automator script that accepts a file from a folder action and changes ownership of that file. (My printer sends scans to my Mac that are owned by root). I have a shell script that works fine in terminal, but won't work in the automator workflow. Attached is the workflow as well as the error message. The workflow doesn't seem to have an error, but it doesn't work either!

@Barney-15E: Solved it! "Pass input" was set to stdin. I was looking at the shell script and realized that it was expecting arguments. Changed that parameter and works great. Thanks for making me look at it deeper.

You don't need the "Get selected Finder items" action as the file is passed from the Folder Action. However, that is not the problem.
The problem is under Big Sur, processes must ask your permission to access your files. When you run it from Automator, it is running as your users. When it runs automatically, it is not. I don't know what process runs the action, but you would need to give it Full Disk Access in the Privacy & Security System Preferences.
Try FolderActionsDispatcher in the /System/Library/CoreServices folder.

Sorry, I now remember looking at that and did not think about it more intently. I guess I was too focused on it being an access issue.
@Barney-15E I've checked and FolderActionDispatcher does already have access to my Desktop folder. I added. a notification before and after the shell script and the after notification doesn't appear. Still working on it...
