I created S3 bucket and I have added one user in IAM. Suppose my bucuket name sample123. When in bucket ploicy I mentioned resource like below statement user is not able to upload document.

Resource": "arn:aws:s3:::sample123"

But when resource is mentioned in policy as below , the user is able to upload document.

Resource": [ "arn:aws:s3:::sample123","arn:aws:s3:::sample123/*"]

what adding /* to ARN will do in policy. Note : I gave full bucket permissions to the user.
