I am using the following bucket policy for S3

        {
            "Sid": "elasticloadbalanceraccountid",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::127311923021:root"
            },
            "Action": "s3:PutObject",
            "Resource": "arn:aws:s3:::my-access-logs-us-east-1/AWSLogs/${ACCOUNTID}/*"
        },

When I span the NLB using the Cloudformation template, It fails in the NLB creation with the error – Access Denied for bucket: my-access-logs-us-east-1. Please check S3bucket permission (Service: ElasticLoadBalancingV2, Status Code: 400, and does the rollback.

I tried all possibility and also the troubleshooting page from AWS , Still facing the same issue.

1. Any issue with this policy?
2. Since its getting rollback, Is there a way to reproduce this Access Denied using AWS CLI?
3. I use the SSE-KMS, Can this be responsible for the Access Denied error?

Any help on this issue is appreciated.
