I got an error in the AWS Transfer Family documentation fixed

I found an error in the AWS Transfer Family documentation, reported it, and they fixed it.

The following access policy was the target for correction. Can you spot the mistake?

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowListingOfUserFolder",
            "Action": [
                "s3:ListBucket"  
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:s3:::bucket_name"
            ]
        },
        {
            "Sid": "HomeDirObjectAccess",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:GetObject",
                "s3:DeleteObject",
                "s3:DeleteObjectVersion",
                "s3:GetBucketLocation", 
                "s3:GetObjectVersion",
                "s3:GetObjectACL",
                "s3:PutObjectACL"
            ],
            "Resource": "arn:aws:s3:::bucket_name/*"
        }
    ]
}           

The answer is that the s3:GetBucketLocation action was specified for the arn:aws:s3:::bucket_name/* resource. Since this action returns the region where the bucket is located, it must target the bucket resource itself.

Therefore, it was corrected as follows.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowListingOfUserFolder",
            "Action": [
                "s3:ListBucket",
                "s3:GetBucketLocation"
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:s3:::bucket_name"
            ]
        },
        {
            "Sid": "HomeDirObjectAccess",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:GetObject",
                "s3:DeleteObject",
                "s3:DeleteObjectVersion", 
                "s3:GetObjectVersion",
                "s3:GetObjectACL",
                "s3:PutObjectACL"
            ],
            "Resource": "arn:aws:s3:::bucket_name/*"
        }
    ]
}

By the way, I reported the error through the "Provide feedback" link at the bottom of the documentation page.

You can provide feedback from here

Looking back, it might have been better to send a pull request via GitHub so that a record of my contribution would remain. I'll try that if I get another chance.
