Incorrect generation of `_parse_response `

Tái hiện client được tạo bằng cách sử dụng đặc tả OpenAPI được cung cấp, so sánh đường dẫn phân tích response khi response được định nghĩa inline thay vì thông qua một $ref. Theo dõi đường dẫn tạo mã xây dựng _parse_response; hoàn thành khi response 200 được tham chiếu tạo ra TaskSummary.from_dict(response.json()), trong khi các status khác vẫn giữ cách xử lý như mong đợi.

Lovely package BTW!

Describe the bug
Code generation for parsing API response does not generate the code that creates the Python model after the response is completed. This happens when using a $ref to define the response instead of just defining the response body inside the path definition.

      description: |
        Reports status of the task. Lifecycle of a normal task is Created -> PayloadProcessing -> Scheduled -> Completed.
        where PayloadProcessing - the task is going trough additional compilation/validation/optimization, 
        Scheduled - the task is in the qpu queue, Completed - the task has been executed.

the code that gets generated here is:

def _parse_response(*, client: Union[AuthenticatedClient, Client], response: httpx.Response) -> Optional[Any]:
    if response.status_code == HTTPStatus.OK:
        return None
    if response.status_code == HTTPStatus.BAD_REQUEST:
        return None
    if response.status_code == HTTPStatus.FORBIDDEN:
        return None
    if client.raise_on_unexpected_status:
        raise errors.UnexpectedStatus(response.status_code, response.content)
    else:
        return None

which is not correct. The additional context shows the expected behavior.

Additional context
Note if I modify the path:

  /v2/task/{task_id}:
    get:
      summary: Get the summary of a task.
      responses:
        '200':
          description: Summary of the task at the time the request was made.
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/TaskSummary'
        '400':
          $ref: '#/components/responses/bad_request'
        '403':
          $ref: '#/components/responses/not_authorized'
      parameters:
        - $ref: '#/components/parameters/task_id'

it generates the correct code:

def _parse_response(
    *, client: Union[AuthenticatedClient, Client], response: httpx.Response
) -> Optional[Union[Any, TaskSummary]]:
    if response.status_code == HTTPStatus.OK:
        response_200 = TaskSummary.from_dict(response.json())

        return response_200
    if response.status_code == HTTPStatus.BAD_REQUEST:
        response_400 = cast(Any, None)
        return response_400
    if response.status_code == HTTPStatus.FORBIDDEN:
        response_403 = cast(Any, None)
        return response_403
    if client.raise_on_unexpected_status:
        raise errors.UnexpectedStatus(response.status_code, response.content)
    else:
        return None
