Add else block when getResponse.isSourceEmpty is true to call actionListener.onFailure() instead of silently dropping the request. Without this, the listener is never notified and the thread hangs. Signed-off-by: Manaswini Ragamouni <ragamanu@amazon.com>

Add else block in TransportExecuteMonitorAction when
getResponse.isSourceEmptyis true. Without this, the action listener is never notified when the monitor source is empty, causing the thread to hang indefinitely and potentially dropping nodes.Related Issues
