Rest api requires "enum" word at the end of the enum

Hi ahtahkr 

You should be able to use `black` and not `blackenum`, it sounds like a typo.

Here is a minimal example, see if it helps...

openapi: 3.0.0
info:
  title: Test API
  version: 1.0.0

paths:
  /color/{color}:
    get:
      description: Get the hex of a color
      parameters:
      - name: color
        schema:
          $ref: '#/components/schemas/Color'
        required: true
        in: path
      responses:
        default:
          description: Hex code of a color.
          content:
            application/json:
              schema:
                type: string
                example: '#112233'
            
components:
  schemas:
    Color:
      type: string
      enum:
      - black
      - brown
      - red
      - blue
