Starting in September 2020, AWS supports the creation of S3 storage buckets that do not support ACLs.This means that you cannot specify ACL parameters (such as public-read) when uploading files.

if I add "--acl public-read", I will get the error "An error occurred (AccessControlListNotSupported) when calling the PutObject operation: The bucket does not allow ACLs".

But If I don't add "--acl public-read", It works out.

So hopefully, either take a look at it in code or modify README.md to remind users
