  <p>the <code>xxljobmysql</code> entryPoint is the new TCP entryPoint I wanted to add. But when I check on the Dashboard, It tell me:</p>
  <pre><code>entryPoint &quot;xxljobmysql&quot; doesn't exist
  no valid entryPoint for this router
  </code></pre>
  <p>am I missing something and what should I do to fix it add make it work as expect?</p>
