Building fails with "childName cannot be empty" #7876

Description

What are you generating using Kiota, clients or plugins?

API Client/SDK

In what context or format are you using Kiota?

Mac executable

Client library/SDK language

Go but I don't think it's specific to Go

Describe the bug

Building a client in version 1.32.4 fails with the following error:

crit: Kiota.Builder.KiotaBuilder[0]
      error generating the client: One or more errors occurred. (One or more errors occurred. (The value cannot be an empty string. (Parameter 'childName')))

Expected behavior

A client should be generated without an error

How to reproduce

kiota generate -l go -c TestClient -n test_bug/client -d ./spec.yml -o ./client

Using the following spec

Open API description file

openapi: '3.0.2'

                items:
                  type: object

Kiota Version

1.32.4

Latest Kiota version known to work for scenario above?(Not required)

No response

Known Workarounds

The error disappears both if the I remove the trailing slash in the path, and if the items subschema is removed or moved to a component reference. So I guess it has something to do with generating inline component schemas.
