title: Generated Access Token invalid for Demo Video Application
body: <p>I am using the sample Video application pulled from GitHub. I am using a node.js server to supply the sample application with the access token. When I use the Twilio Console to generate a video access token and put it in my Node.js server as a literal and return it I am able to run the example application and connect to a room. If I use the sample token generation code in my Node.js server I get 'Invalid Access Token' back in an exception in the onDisconnected method in the Room.Listener. </p>
  
  <p>The following code is what is running in the server to create the access token, I also found a different sample which I tried as well. I have gone back and verified that my data values for the account SID and the API keys are correct. I have a similar method running returning the VoiceGrant access token and that is working, but something about this VideoGrant one is off, I just do not see it. </p>
  
  <pre><code>// ***********************************************************************************
  // ***********************************************************************************
  // Video Access Token
  // ***********************************************************************************
  // ***********************************************************************************
  var videoCallAccessToken = function(request, response) {
          console.log('/twilio/video/accessToken');
          var accessToken = makeVideoAccessToken();
          response.writeHead(200, {'Content-Type': 'text/plain'});
          response.end(accessToken);
          console.log(accessToken);
  };
  
  app.get('/twilio/video/accessToken', videoCallAccessToken);
  
  var makeVideoAccessToken = function() {
          const AccessToken = twilio.AccessToken;
          const VideoGrant = AccessToken.VideoGrant;
          const grant = new VideoGrant({configurationProfileSid: accountData.videoConfigurationProfileSid});
          const accessToken = new AccessToken(accountData.sid, accountData.videoApiSid, accountData.videoApiSecret);
          accessToken.identity = 'ABC123';
          accessToken.addGrant(grant);
          return accessToken.toJwt();
  };
  </code></pre>
  
  <p>FYI...I plan to alter the identity generation, but have not got there yet.</p>
  
  <p>Thanks,</p>
