title: 500 Error With Youtube API
body: <p>I am trying to edit my channel description using the Youtube Data API V3, but I get a "500 Internal Server Error" if I try to do anything with "brandingSettings". I even tried starting a private browsing session and using a different Google account. Is this a Google issue that will be fixed soon? Or am I doing something wrong?</p>
  
  <p>EDIT: Sorry, I am new. I am just using the "Try It!" thing on developers.google.com.</p>
  
  <p>Request:</p>
  
  <pre><code>PUT https://www.googleapis.com/youtube/v3/channels?part=brandingSettings&amp;key={API_KEY}
  
  {
  "brandingSettings": {
  "channel": {
  "description": "testing"
  }
  }
  }
  </code></pre>
