Cannot upload using TestDemo script

Hello Jess,

I am following the workflow tutorial, i was able to generate a token id and now trying to send the data usng that id as a next step. I get the following:

KalturaFullClient.min.js:684 Uncaught TypeError: Cannot read property '0' of undefined
    at KalturaRequestBuilder.doHttpRequest (KalturaFullClient.min.js:684)
    at KalturaRequestBuilder.execute (KalturaFullClient.min.js:694)
    at test3.html:26
    at Object.success (KalturaFullClient.min.js:690)
    at i (jquery.min.js:2)
    at Object.fireWith [as resolveWith] (jquery.min.js:2)
    at A (jquery.min.js:4)
    at XMLHttpRequest.<anonymous> (jquery.min.js:4)

Here is my js code:

  6 var config = new KalturaConfiguration();
  7 config.serviceUrl = 'http://....';
  8 var client = new KalturaClient(config);
  9 KalturaSessionService.start(
 10     "...",
 11     "....",
 12     2,
 13     101)
 14 .execute(client, function(success, ks) {
 15   if (!success || (ks.code && ks.message)) {
 16     console.log('Error starting session', success, ks);
 17   } else {
 18     client.setKs(ks);
 19     var uploadTokenId = "0_5bb8755914bc3175eb90692664929484";
 20     var fileData = "/var/www/html/js/a.flv";
 21     var resume = false;
 22     var finalChunk = true;
 23     var resumeAt = -1;
 24 
 25     KalturaUploadTokenService.upload(uploadTokenId, fileData, resume, finalChunk, resumeAt)
 26       .execute(client, function(success, results) {
 27         if (!success || (results && results.code && results.message)) {
 28           console.log('Kaltura Error', success, results);
 29         } else {
 30           console.log('Kaltura Result', results);
 31         }
 32       });
 33 
 34   }
 35 });
