Problem description

This error occurs during a multipart upload that uses an S3 SDK. The error indicates that the Content-Encoding is set to aws-chunked and is incompatible with the x-amz-content-sha256 value.

Cause

This error is triggered during a multipart upload that uses an S3 SDK if the request header meets the following conditions:

Content-Encoding is set to aws-chunked.
The value of x-amz-content-sha256 is incompatible with aws-chunked encoding.

When OSS processes a request that uses aws-chunked encoding, the x-amz-content-sha256 parameter must be set to a specific value, such as STREAMING-AWS4-HMAC-SHA256-PAYLOAD. If an unsupported value is used for x-amz-content-sha256, the request is denied.

Example

In the following request, the Content-Encoding header is set to aws-chunked, but the x-amz-content-sha256 header has an incompatible value:

PUT /example-object HTTP/1.1
Host: example-bucket.oss-cn-hangzhou.aliyuncs.com
Content-Encoding: aws-chunked
x-amz-content-sha256: UNSIGNED-PAYLOAD
x-amz-date: 20240320T103000Z
Transfer-Encoding: chunked
Authorization: AWS4-HMAC-SHA256 Credential=...

[Chunked Body]

The returned error message is as follows:

Solutions

If you use aws-chunked encoding, set x-amz-content-sha256 to STREAMING-AWS4-HMAC-SHA256-PAYLOAD.
If you do not need aws-chunked encoding, remove the Content-Encoding request header or set it to a different value.
Use the standard OSS multipart upload method instead of the aws-chunked encoding attribute from the S3 SDK.
Make sure the S3 SDK version you use supports the OSS implementation of aws-chunked encoding. Update to the latest version if needed.
