I've been trying to reproduce simple custom drilldown behavior as documented in https://dev.splunk.com/enterprise/docs/developapps/webframework/codeexamplefw/splunkjsstack/drilldow... but nothing appears to work for me (that is, 1- click events in my chart don't seem to be producing any effects in the console; 2- the default onDrilldown function only appears to get called from one of the charts in my page -and produces an error-.
What could be wrong? (note: I'm simply trying to produce some custom logging behavior at this point).
