Hi all,
The COS objstore support is implement via github.com/mozillazg/go-cos at 2019 year,
the mozillazg/go-cos is unfficial and not actively update now, it's latest tag version date is 2019-09-18.
the official sdk github.com/tencentyun/cos-go-sdk-v5 which based on mozillazg/go-cos is keeping actively update, the latest tag date is 2021-09-07.

It should be change to official SDK to get more support. I fix testing bucket name bug and setRange bug, then it has passed the e2e objectore test.

thanks to @jojohappy and mozillazg/go-cos author.
