Description
Under storm ui "Topology summary" lastError is not getting populated, you need to go into "Component summary"
Seems some body raised a similar question here https://github.com/apache/storm/pull/2828#issuecomment-420790179
STORM-3217 fixed the component page, but not the topology page
is it because it is missing here https://github.com/apache/storm/blob/v2.1.0/storm-webapp/src/main/java/org/apache/storm/daemon/ui/UIHelpers.java#L1225
I see it is in this section added https://github.com/apache/storm/blob/v2.1.0/storm-webapp/src/main/java/org/apache/storm/daemon/ui/UIHelpers.java#L1480
