When an exception is encountered in the Ambari View (say Ambari Slider View), it shows up as a banner with red-text in the top. However there are instances when there is no corresponding log or stack trace dumped in /var/log/ambari-server/ambari-server.log. This happens even if the ambari-server log level is bumped up to DEBUG.
This behavior was primarily noticed in a secured cluster.
Please see attached screenshots as reference to the exception seen in the View UI.
