Yeah. I also noticed it. Not sure if is there a way to report the issue to the content creators for them to update.
Yes, i also was wondering,. The bucket name is part of the prefix. In the aws doc (linked in the session) you find this example:
For example, if an object (123.txt) is stored as BucketName/Project/WordFiles/123.txt, the prefix is “BucketName/Project/WordFiles/”
Yes, S3 prefix also includes the parental bucket name of an S3 object, whereas S3 key only has folder names (if any) and the object name.
