rclone does not support empty directories on S3.
often requested feature and much discussed in the forum.
https://forum.rclone.org/t/how-to-rclone-copy-empty-folders-directories/14081
https://github.com/rclone/rclone/issues/4423
is this a one time transfer or something to be done on a schedule?
you could write a script that:
- for each empty dirs on gdrive, copy a file to it.
rclone copy
- delete those files from aws
