S3Sync: Source bucket: prod_bucket_A to Destination bucket: prod_bucket_B failed fatal error:S3SYNC An error occurred (AccessDenied) when calling the ListObjectsV2 operation: Access Denied

When trying to synchronize two buckets in CPM I get the following error message.
S3Sync: Source bucket: Prod_bucket to Destination bucket: Dev_bucket failed fatal error: S3SYNC An error occurred (AccessDenied) when calling the ListObjectsV2 operation: Access Denied 

This error is caused by an issue with the S3:ListBuckets permission. You should update the role/user permissions using the latest CPM JSON Permisison files located at this link.
