Strange JSON in the "Request body" of API endpoints in LLMs.txt files

CLI Version (from fern.config.json)

0.50.13, also 0.46.22

Minimal API Specification

openapi: 3.1.0
info:
  title: LLMs.txt issues
  version: 1.0.0
servers:
  - url: https://example.com/v1

paths:
  /something:
    post:
      summary: Create something
      requestBody:
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/Foo'
      responses:
        '200':
          description: OK
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Foo'

components:
  schemas:
    Foo:
      type: object
      properties:
        id:
          type: integer
        bar:
          type: string

Actual UI Behavior

/llms-full.txt and the .mdx file for that sample endpoint contain the following text. Note that the "Request Body" JSON is very strange - it's neither the schema definition not a valid request body example.

# Create something

`` `http
POST https://example.com/v1/something
Content-Type: application/json
`` `



## Request Body

`` `json
{"type":"alias","value":{"type":"id","id":"type_:Foo"}}
`` `

## Response Body

- 200: OK

## Examples

`` `shell
curl -X POST https://example.com/v1/something \
     -H "Content-Type: application/json" \
     -d '{}'
`` `

Expected UI Behavior

"Request Body" section in .mdx and /llms-full.txt contains either the body JSON Schema or a valid sample request body.

Steps to Reproduce

1. Create a docs project with the OpenAPI spec provided above.
2. Publish the docs.
3. Open the page for the POST /something endpoint and append .mdx to the page address.
4. Check the JSON in the "Request Body" section.
