Minimal API Specification

openapi: 3.0.0
info:
  title: Demo API
  version: "0.1"
paths:
  /v2/conversations:
    post:
      operationId: createConversation
      requestBody:
        content:
          multipart/form-data:
            schema:
              type: object
              properties:
                files:
                  type: array
                  description: Files with local file paths
                  items:
                    type: string
                    format: binary

      x-fern-examples:
        - code-samples:
            - language: curl
              code: curl https://yahoo.com/
            - language: python
              code: print("hello”)

Actual UI Behavior

There’s no dropdown to pick the language for the sample code, and the sample code provided in openapi.yaml is ignored. Fern-generated code is shown instead.

Expected UI Behavior

There should be a dropdown to pick the language for the sample code, and the sample code provided in openapi.yaml should be displayed.

Steps to Reproduce

Start up a docs site with this openapi.yaml and visit the API reference page for Conversations/post.

This is a high-priority issue for us, since we rely on hand-written, heavily commented SDK sample code in the API reference pages to serve as the main reference material for our SDK.
