+Management::
+* The watch API considers an index action without a defined index name to be valid, but the Watcher UI 
+didn't validate accordingly. This resulted in a bug manifested as the UI rejecting attempts to create 
+Advanced Watches and Threshold Watches with this configuration, and as displaying watches configured 
+this way via Console with "Config error" states in the watches table. This change fixes the bug so that 
+the UI accepts watches that are configured with index actions without a defined index name {kibana-pull}74684[#74684]
