> Let's say there are three keys:
>  * subdir_1/
>  * subdir_1/subdir_1_1/
>  * subdir_1/subdir_1_1/readme.md
> Prefix is subdir_1/
> When delimiter query parameter is empty string (""), all the keys are returned as CommonPrefixes instead of the supposed Contents.

> When the delimiter query parameter is removed, it returns the expected data
> !image-2023-03-16-15-49-48-168.png|width=419,height=460!
> The problem was encountered when a user is trying to use Minio S3 client commands with recursive flag (e.g. {{{}mc cp -r{}}}). Minio client sends empty string as delimiter instead.
