我有一个简单的API，它有一个post端点，需要三个参数。当我通过python-fask codegen SwaggerUI测试它时，我得到一个错误，说没有足够的值来解包。server-stub是从swagger-hub自动生成的，预计可以工作：）如何让它工作？以下是详细信息：

来自swagger yaml文件：

paths:
  /estimate:
    post:
      tags:
      - client_requests
      summary: submits a job by specifying a script file
      operationId: e_post
      requestBody:
        content:
          application_json: #WRONG should be application/json as I later discovered.
            schema:
              $ref: '#/components/schemas/EJob'
      responses:
        "201":
          description: job_received
        "400":
          description: invalid_input
      callbacks:
        statusUpdate:
          '{$request.body#/callback_url}':
            post:
              requestBody:
                content:
                  application_json:
                    schema:
                      $ref: '#/components/schemas/EJobStatus'
                required: true
              responses:
                "200":
                  description: Accepted by the server
      x-openapi-router-controller: swagger_server.controllers.client_requests_controller

和yaml中的Ejob Schema：

schemas:
    EJob:
      required:
      - callback_url
      - id
      - script_url
      type: object
      properties:
        id:
          type: integer
          format: int64
          example: 39
        script_url:
          type: string
          description: A job for backend to execute
          format: uri
          example: file:///data/39_script.json
        callback_url:
          type: string
          description: This URL is called to update status
          format: uri
          example: http:://192.168.100.30:50/update_status

来自Swagger UI的post请求：

curl -X 'POST' \
  'http://localhost:8080/BLA/BLA/1.0.0/estimate' \
  -H 'accept: */*' \
  -H 'Content-Type: application_json' \
  -d '{
  "callback_url": "http://192.168.100.30:50/update_status",
  "id": 39,
  "script_url": "file:///data/39_script.json"
}'

我从swaggerhub python-flask codegen生成的代码中得到的错误：
