title: Power BI Web.Contents Timeout
body: <p>The data returned from my web service is a bit large. I am experiencing Timeout error(it says after 3.0 seconds) on Power BI Desktop even though I already added Timeout before my Headers parameter below. Is there something wrong with the following? </p>
  
  <p>I am not experiencing any Timeout issues if I delete my source to a few hundred rows.</p>
  
  <pre><code>let
      Source = Json.Document(Web.Contents("url",
      [
          Timeout=#duration(0,0,30,0),
          Headers=[#"x-api-key"="somekey"]
      ]
      ))
  </code></pre>
