Release Kingston and later versions Cause When you click on "Manage Pattern" the URL that is redirected would look like: http://<Instance-name>.service-now.com/$sw_pattern_debugger.do?........./ Please observe the $sw_pattern_debugger.do in the URL. This is older version of the pattern debugger page and it is replaced by new version. This is the reason it fails to open. Resolution The page $sw_pattern_debugger.do is replaced by '$sn_pattern_designer.do'. So the new URL would look like: http://<Instance-name>.service-now.com/$sn_pattern_designer.do?........./The new version of the page can be used by navigating to Pattern Designer -> Discovery patterns. With this, pattern debugger should be opened properly. Additional Information Troubleshoot pattern-related mapping errors
