I am not seeing it, where am I going wrong with the code?

I am working on a workflow to reconfigure a vCenter alarm to add a SNMP receiver, port and community.  Actually I need this in two part, first to check to see if it is already configured and compare to what is presented to make sure the config is correct or to fix it.  First step, getting the alarm to update.  I was using Onyx to help with the code but I keep getting this error

[2015-04-07 21:14:02.009] [I] TypeError: Cannot find function reconfigureAlarm in object DynamicWrapper (Instance) : [VcFolder]-[class com.vmware.vmo.plugin.vi4.model.VimFolder] -- VALUE : Folder<group-d1>. (Workflow:Copy of Alarms - Host Connection and Power / Scriptable task (item1)#57)

This workflow scripting task takes this variable  vc = VC:SDKConnection

Where in the world am I going wrong?

//System.log(vc.alarmManager.vimType)
var alarm = vc.alarmManager.getAlarm()
for each ( var a in alarm ){
System.log(a.info.name)

var alarmEntity = a.info.entity
var alarmType = a.vimType
System.log("Found Alarm Entity: "+alarmEntity)
break;;
}

//System.log(alarmEntity)
