title: SwaggerHub mock always returns the same id - is this expected?
body: <p>I created a very simple OpenAPI docs as I have just started learning about it.</p>
  <p>This is the link: <a href="https://app.swaggerhub.com/apis-docs/srki.coric/Shopping_Cart/1.0.0" rel="nofollow noreferrer">https://app.swaggerhub.com/apis-docs/srki.coric/Shopping_Cart/1.0.0</a></p>
  <p>There is a mock server however, my expectation was that if I do a POST request with certain data, that the response will contain that data, and that <code>_id</code> would be auto-generated, but the response is always the default one.</p>
  <p>Is this the expected behavior or I am doing something wrong?</p>
