AWS S3 Plugin - Action "Put Object"


has anyone used the AWS S3 plugin and tried to upload files to a bucket via the “put object” action? I’m trying to figure out which fields are required to perform the action. According to the plugin documentation the only required field is “Key” and if I only use this one, it works :). But once I try to add something to the body field it starts to fail. Perhaps someone uses it and could post the fields that are required to upload files. I’d like to create a workflow to backup my workflows. Something similar to the Backup-Active-Workflows-to-Github workflow (Rapid7 Extensions) but using S3.
