It seems that a pager created using NewListBlobsFlatPager should not perceive any hierarchical structure, as it is designed to return a flat list of blobs. I’m not entirely sure why this error is occurring, so could you provide more details？

The encountered issues are described in the issue raised #446 . I have also included the configurations I used. Could you please review them and let me know if any additional details are needed?

We have a similar implementation for deletion on Azure, but I haven’t encountered any issues like this. Moreover, Milvus doesn’t seem to use hierarchical deletion either. This error might be caused by other reasons. The hierarchical deletion approach doesn’t align well with the flat data structure used by object storage systems like S3. Let me double-check and get back to you.
