MinIO won't fix either.

Cloudberry shouldn't be making the HEAD call on upload.

Cloudberry should ignore the PutObjectACL error. Perhaps an option to do that? Or simply not make that call.

Basically, Cloudberry calls both PutObjectACL and HeadObject and MinIO doesn't implement either of them.

I filed a bug: https://github.com/minio/minio/issues/18636

this appears to be a bug in the MinIO server since it works on all other sites.
