Projection result not working

EventStoreDB
1

Hello guys

I created the following continuous projection. I expected that an empty array would be returned but nothing is return.

The stream Subscription has one event. SubscriptionCreated. However I want to build a projection on event SubscriptionApproved. However I expected the subscription result to return an empty array and it is not.

fromCategory(‘Subscription’)
.when({
$init: function () {
return [];
}
}).outputState();

Try adding a handler into the projection

fromCategory(‘Subscription’)
.when({
$init: function () {
return [];
},
'SubscriptionApproved' : function(s,e){
}
}).outputState();
