As Peter already suggested that , export the whole app and then import into another environment. It worked for me as well and meanwhile you can raise a ticket with Appian Support team.</p><div style="clear:both;"></div>https://community.appian.com/thread/90943?ContentTypeID=1Thu, 10 Feb 2022 17:50:30 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:36a96576-7668-4c7c-8223-979c53349529Peter Lewis<p>I&#39;d suggest&nbsp;opening a support ticket to have the support team investigate further. One other alternate is to try a manual import / export instead of using Compare + Deploy</p><div style="clear:both;"></div>
