$ref to another file throws: Circular reference detected while resolving schema

[esd-thg]

What are you generating using Kiota, clients or plugins?

API Client/SDK

In what context or format are you using Kiota?

Nuget tool

Client library/SDK language

Csharp

Describe the bug

Kiota doesn't seems to like nested $refs that point to other files (fragments).
Running kiota with the provided openapi throws this error:

 crit: Kiota.Builder.KiotaBuilder[0]
       error updating the client: Circular reference detected while resolving schema: error.openapi.json#/schemas/ErrorResponse

Expected behavior

Should work

How to reproduce

dotnet kiota generate -l CSharp -d <given openapi>

Known Workarounds

referencing the fragment directly seems to work, instead of referencing the schema that then references the fragment

{
  "paths": {
    "/foo": {
      "get": {
        "responses": {
          "400": {
            "description": "Bad Request",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "error.openapi.json#/schemas/ErrorResponse" // <-- direct
                }
              }
            }
          }
        }
      }
