How to be able to use System Entity, in fulfillment, in Dialogflow?

Question

I am getting undefined, when using agent.parameters.geo-country while using the System entity @Sys.geo-country.

This is the error I am getting.

JSON property syntax (x.y.z) doesn't like the dash. In order to get around that, you can use the alternative bracket syntax (x['y']['z'])

In your case, you could use agent.parameter['geo-country'].

Another thing you can do instead is look at the name of the paramter, and change it if you want.

For example, in the case below, the entity type is @sys.any, but I've named it to search. This means I could instead use agent.parameter.search which may be more useful to me.
