title: Route defined in Swagger specification (/sales) but there is no defined get operation
body: <p>I am creating APIs with importing existing APIs from swagger JSON file to a Bluemix API Connect environment. When I use Invoke to test a post API I get the following error:</p>
  
  <blockquote>
    <p>405 Method Not Allowed Content-Type: text/html Error: Route defined in
    Swagger specification (/sales) but there is no defined get
    operation.<br> &nbsp; &nbsp;at send405
    (/home/vcap/app/node_modules/swagger-tools/middleware/swagger-router.js</p>
  </blockquote>
  
  <p>Any experience with POST request with Bluemix API Connnect? </p>
