title: Youtube API response with internal 500
body: <p>I have been using Youtube API with v3 version to get playlist of youtube.</p>
  
  <p>example url:
  <a href="https://www.googleapis.com/youtube/v3/playlistItems?playlistId=xxxxxxxxx" rel="nofollow noreferrer">https://www.googleapis.com/youtube/v3/playlistItems?playlistId=xxxxxxxxx</a></p>
  
  <p>But I found sometime Youtube API response with error message "500 Internal Server Error"</p>
  
  <p>How can I fix or prevent this error from using Youtube API?</p>
