Object Storage Service:0042-00000301

Problem description

The x-oss-copy-source header in the UploadPartCopy request has an invalid value.

Causes

The value of x-oss-copy-source must start with a forward slash (/). The header accepts the following formats:

• /bucket-name/object-name — copy from the latest version of the source object

• /bucket-name/object-name?versionId=<version-id> — copy from a specific version of the source object

If the value does not start with /, OSS rejects the request with this error.

Examples

The following request fails because the x-oss-copy-source value does not start with /:

PUT /multipart.data?partNumber=1&uploadId=0004B9895DBBB6EC98E36  HTTP/1.1
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Content-Length: 6291456

Authorization: OSS qn6q**************:77Dv****************
x-oss-copy-source: oss-example/src-object
x-oss-copy-source-range:bytes=100-6291756

Solutions

Add a leading / to the x-oss-copy-source value:

PUT /multipart.data?partNumber=1&uploadId=0004B9895DBBB6EC98E36  HTTP/1.1
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Content-Length: 6291456
