S3 error when sending post request

[antoniogmartin]

Hi,
I am using ONTAP S3 ( 9.10.1v ) that is failing when it tries to create to store an object:
Kubeflow version is 1.7
The ml-pipelines api-server is: "ml-pipeline/api-server:2.0.0-alpha.7"
Here is the error:

InternalServerError: Failed to store pipelines/465e9545-df3a-4033-a838-ba7a14c16c65: x-amz-content-sha256 must be UNSIGNED-PAYLOAD or a valid sha256 

I've seen this errors ocurs because there is a required header missing in the post request with the value " x-amz-content-sha256" or "UNSIGNED-PAYLOAD". This is required by AWS Signature Version 4. rclone/rclone#5422

Here is another option, include in the s3 client the following key "applyChecksum: false"
aws/aws-sdk-js-v3#3254

Is there any workaround to make ONTAP compatible with kubeflow pipelines?
