title: UIPath Add Data Row of DataTable with possibly non existent item in ArrayRow
body: <p>In my Add Data Row activity I am using the following for my ArrayRow</p>
  <pre><code>{item(&quot;ref&quot;).ToString,
  Convert.ToString(GID_LimitedData.Rows(ICS_RowIndex)(2)),
  Convert.ToString(GID_LimitedData.Rows(ICS_RowIndex)(3)),
  item(&quot;price&quot;).ToString
  }
  </code></pre>
  <p>My problem is that sometimes item(&quot;ref&quot;).ToString will not exist and sometimes it will.</p>
  <p>Currently the error I get when it does not exist is:</p>
  <pre><code>Add Data Row: Element 'price' not found.
  </code></pre>
  <p>I would be interested in workaround or also best practices for this situation. Thanks for the help</p>
