`s3-credentials create name-of-bucket --create-bucket --public` fails with error about s3-credentials HOT 4 CLOSED

Would create bucket: 'simonw-test-public-access2'
... then this public access block configuration:
{"BlockPublicAcls": false, "IgnorePublicAcls": false, "BlockPublicPolicy": false, "RestrictPublicBuckets": false}
... then attach the following bucket policy to it:
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowAllGetObject",
            "Effect": "Allow",
            "Principal": "*",
            "Action": [
                "s3:GetObject"
            ],
            "Resource": [
                "arn:aws:s3:::simonw-test-public-access2/*"
            ]
        }
    ]
}
Would create user: 's3.read-write.simonw-test-public-access2' with permissions boundary: 'arn:aws:iam::aws:policy/AmazonS3FullAccess'
Would attach policy called 's3.read-write.simonw-test-public-access2' to user 's3.read-write.simonw-test-public-access2', details:

Would call create access key for user 's3.read-write.simonw-test-public-access2'
