I am trying to create a dialog in my outlook add-in. I got this error from the browser console of the dialog while loading office scripts. The dialog contains a simple html page with jquery and office scripts references in the header.

TypeError: can't redefine non-configurable property "context" outlook-web-16.01.js:19:9756

This is the source code of the dialog page

  <body>
    <script>
      (function () {
        console.info("Test Dialog");
        Office.initialize = (reason) => {
          $(document).ready(function () {
            Office.context.ui.messageParent(true);
          });
        };
      })();
    </script>
  </body>
</html>

How can I resolve this issue?

Include a single version of Office js.

Change 

<script src="https://appsforoffice.microsoft.com/lib/beta/hosted/office.debug.js"></script>
<script src="https://appsforoffice.microsoft.com/lib/1.1/hosted/office.js"></script>

to 

<script src="https://appsforoffice.microsoft.com/lib/beta/hosted/office.debug.js"></script>

or

<script src="https://appsforoffice.microsoft.com/lib/1.1/hosted/office.js"></script>
