I'm getting the following error when my action run.

Error: No files were found with the provided path: backups/backup.tar.gz. No artifacts will be uploaded.

Version: v0.4

Here is my .yml action code (note: I have a monorepo and 'studio' is the folder where Sanity resides):

    # Runs at 06:00pm EST everyday
    - cron: '0 18 * * *'
