## Return Type and Data Filtering { #return-type-and-data-filtering }

Let's continue from the previous example. We wanted to **annotate the function with one type**, but we wanted to be able to return from the function something that actually includes **more data**.

You can check it at <a href="http://127.0.0.1:9999/api/v1/docs" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/docs</a>:

Right as we wanted it. ✔️

This is because FastAPI uses this `root_path` to create the default `server` in OpenAPI with the URL provided by `root_path`.

- Fixed a bug with dual stack clusters using the beta feature MultiCIDRServiceAllocator which could not create dual stack Services or Services with IPs in the secondary range. Users who wanted to use this feature in version 1.30 with dual stack clusters could work around the issue by setting the feature gate DisableAllocatorDualWrite to true.
