UploadPartCopy does not support source objects that are directory-type in a hierarchical bucket or objects ending with / in a regular bucket when the target is an object in a hierarchical bucket.

Root cause

When initiating an UploadPartCopy request, the following situations may occur:

The source is a directory-type object in a hierarchical bucket, and the target is an object in a hierarchical bucket.

The source is an object ending with / in a regular bucket, and the target is an object in a hierarchical bucket.

Example

PUT /DestObjectName HTTP/1.1​
Host: <Bucket name>.<TOS endpoint>​
Date: Fri, 30 Jul 2021 08:05:36 +0000​
Authorization: authorization string​
x-tos-copy-source: /sourcebucketname/SourceObjectName​

Solution

If the source is a hierarchical bucket, use an object that is not a directory type; if the source is a regular bucket, use an object that does not end with /.
