Hello, I encountered a response-body validation error. The server/producer defines the "400 Bad Request" response body as follows:

responses:
  error-400-bad-request:
    description: ''
    content:
      application/vnd.api+json:
        schema:
          type: object
          properties:
            errors:
              type: array
              items:
                type: object
                properties:
                  source:
                    type: object
                    properties:
                      parameter:
                        type: string
                      pointer:
                        type: string
                  code:
                    type: string
                    enum:
                      - BAD_REQUEST
                      - UNPROCESSABLE_ENTITY
                  status:
                    type: string
                    enum:
                      - '400'
                      - '422'
                  details:
                    type: string
                required:
                  - code
                  - status
          required:
            - errors
        examples:
          Example 1:
            value:
              errors:
                - source:
                    parameter: id
                  detail: is in invalid format
                  code: BAD_REQUEST
                  status: '400'

Example:

{
  "errors": [
    {
      "source": {
        "parameter": "id"
      },
      "detail": "is in invalid format",
      "code": "BAD_REQUEST",
      "status": "400"
    }
  ]
}

The client/consumer used the following mocked response body:

{
  errors: [
    {
      status: "400",
      code:   "INVALID_QUERY_PARAMETER",
      source: {
        params: "foobar"
      }
    }
  ]
}

It expected the undefined

params

instead of

parameters

, but pactflow didn't detect an error.

Have you checked your “additionalProperties” parameter?
