  <p>Can you help me troubleshoot this ? I have setup the twitter account for read-write access and have provided the values for <code>consumerKey</code>, <code>consumerSecret</code>, <code>accessToken</code> and <code>accessTokenSecret</code> as per the <a href="http://www.mulesoft.org/documentation/display/current/Configure+Twitter+for+API+Access" rel="nofollow">mulesoft documentation</a>.
  <br/>
  TIA</p>
