title: Unable to trigger web request implemented in Giraffe
body: <p>I'm struggling to trigger a web service that's written in Giraffe.</p>
  
  <p>Here's the code:</p>
  
  <pre><code>let webApp : HttpContext -&gt; HttpHandlerResult = 
  
      choose [
          GET &gt;=&gt;
              choose [ routef "/platforms/" fetchPlatforms ]
  </code></pre>
  
  <p>fetchPlatforms is implemented as follows:</p>
  
  <pre><code>let private fetchPlatforms () (context : HttpContext) =
      async { let response = getPlatforms()
              return! json response context
      }
  </code></pre>
  
  <p>The issue that I'm running into is that when I run the server code and then attempt to test the web service, I get the following message:</p>

  <p><strong>Update:</strong></p>
  
  <p>I am only observing this issue in VS Code.</p>
  
  <p>Hence, I can observe a successful web request and response using Visual Studio 2017 (3) version 15.4</p>
  
  <p>Here's the <a href="https://www.youtube.com/watch?v=s2952vnPXmE" rel="nofollow noreferrer">video</a> that demonstrates the difference between VS2017 and VS Code</p>
