title: getItemOrNullObject() throwing Permission denied message
body: <p>I am having an issue with the <code>Excel.WorksheetCollection.getItemOrNullObject(key: string)</code> function from the Office js API. As you can see from my code below, I am looking for a sheet named <code>Meta</code> in the current workbook and if it doesn't exist, it will create one.</p>
  <p>My problem is that for some reason the <code>getItemOrNullObject</code> function doesn't return an Excel.Worksheet or null in absence of the Meta sheet. Instead, when I log the variable I get this message with a bunch of <code>Permission denied</code>s:</p>

  <p>I have unfortunately not seen this anywhere else online and I can't figure out where the issue lies.</p>
  <p>Does anybody know how to solve this ?</p>
  <p>Thank you for reading.</p>
