Authorization mechanism you have provided is not supported. please use aws4-hmac-sha256

 When you work with AWS SDK or AWS S3 compatible storage, during the time of connection settings you may encounter this error 

authorization mechanism you have provided is not supported. please use aws4-hmac-sha256

I got this error when I tried to add a storage in Cloudberry tool. The destination is Oracle Object storage.

How to solve this error?

This is because of the signature version used is old. You need to Click on the "Advanced Settings", then on drop down of Signature version, choose 4.
