What is the problem you are having with rclone?
I'm syncing files from local to AWS s3 using Rclone. Can rclone execute sync without creating config file ? I mean by passing aws accesskey, secret key etc as part of the body ?
I guess the error message is caused by the (newline?) character just before region=
PS: Your IAM access key and secret are visible in the error message, I therefore recommend you immediately delete the access key used above and make a new.
