Trouble Using EnableSubscription() Service

[Ascherer17]

I am trying to enable some subscriptions on a Thing programmatically on ThingWorx 8.4.0.   I wrote a simple service that calls the EnableSubscription service, but it keeps giving me the error: 

Message :: Cannot Update A Subscription That Does Not Exist! - See Script Error Log for more details.

Here's an example setup in which I get the error:

Thing: 'DummyThingEntity'

Property on DummyThingEntity: 'TestNumber1'
Subscription on DummyThingEntity: 

Name: 'Foo'

Event: 'DataChange'

Property: 'TestNumber1'

The subscription simply logs a debug message.

Service on DummyThingEntity: 'Ensub'

 Code: 

me.EnableSubscription({
	thingName: me.name /* THINGNAME */,
	eventName: "DataChange" /* STRING */,
	propertyName: "TestNumber1" /* STRING */
});

Do I have something incorrect in the 'EnableSubscription()' snippet?
