Realtime API Pydantic Models incomplete for RealtimeResponseStatus type

Confirm this is an issue with the Python library and not an underlying OpenAI API

Describe the bug

And I have got errors like this when using latest Azure deployments of OpenAI Realtime model

json

  "type": "response.done",
  "event_id": "event_BvlnvdNtqw7LLGP7xDfyA",

    },
    "metadata": {
      "client_event_id": "response_create_6448171658c7"
    }
  }
}

I have seen online others report errors like this: https://community.openai.com/t/realtime-api-errors-in-both-playground-and-api-calls/1007933 or here https://github.com/pipecat-ai/pipecat/issues/2106#issue-3193722974 etc.

The problem is that the pydantic model for Error is wrong - it does not include the message field (e.g. "We're currently processing too many requests — please try again later." in the above example). This seems to be the case in the API reference itself too https://platform.openai.com/docs/api-reference/realtime-server-events/response/done

A side effect of this is that pydantic validated code sometimes will omit the message which is quite helpeful for debugging.

To Reproduce

Create a response that fails to complete, e.g. due to exceeding the rate limit of your server

The issue is present even in latest code base of openai repo: https://github.com/openai/openai-python/blob/e6c6757553bbdb777c31d0daf5916fb9e2b47ff8/src/openai/types/beta/realtime/realtime_response_status.py#L11
