В конфигурации файла swagger можно получить 2 параметра в пути

У меня проблема с файлом yaml Flask, Connexion и Swagger. Я должен определить путь как: /price/{code1}/{code2}.

В моем файле yaml я установил корневой путь как:

paths:
  /price/{code1}/{code2}:
    get:
      operationId: lib.pack.test
      parameters:
      - in: path
        name: code1
        required: true
        type: string
        description: "code 1"
      - in: path
        name: code2
        reguired: true
        type: string
        description: "code 2"

Когда я запускаю server.py, я получаю эту ошибку:

connexion.exceptions.InvalidSpecification: {'reguired': True, 'in': 'path', 'type': 'string', 'description': 'code 2', 'name': 'code'} is not valid under any of the given schemas

Failed validating 'oneOf' in schema['properties']['paths']['patternProperties']['^/']['properties']['get']['properties']['parameters']['items']:
    {'oneOf': [{'$ref': '#/definitions/parameter'},
               {'$ref': '#/definitions/jsonReference'}]}

On instance['paths']['/price/{code1}/{code2}']['get']['parameters'][1]:
    {'description': 'code 2',
     'in': 'path',
     'name': 'code2',
     'reguired': True,
     'type': 'string'}

Если я удалю {code2}, сервер запустится правильно.

• Питон 2.7
• Колба 1.0.2
• Связь 2.2.0

Это мой код:

Сервер.py

from flask import render_template
import connexion

# Create the application instance
app = connexion.App(__name__, specification_dir = "configuration/")
app.add_api('swagger.yml')
app.run(port=5000, debug=True)


# Create a URL route in our application for "/"
@app.route('/')
def home():
    """
    This function just responds to the browser ULR
    localhost:5000/

    :return:        the rendered template 'home.html'
    """
    return render_template('home.html')


# If we're running in stand alone mode, run the application
if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000, debug=True)

А это Ямл
