title: Swagger:Issue with Path parameter
body: <p>I am try to create a swagger file with the following path:
      paths:
         /v1/customers/{id}/summary :</p>
  
  <p>However I get the following error right off bat:</p>
  
  <p>API requires path parameter but it is not defined: id
  at paths ▹ /v1/customers/{id}/summary</p>
  
  <p>It does not seem to like the 'id' parameter. Could anybody tell me how I could rectify this?</p>
  
  <p>If I drill down on this I see the following:</p>
