Firebase cloud function onUpdate child of list (NodeJs)

问题

How to trigger the firebase cloud function onUpdate

each time any of the child "order_status" is == "accepted"

(included the old Childs on trigger)

my code won't work

Have a look please :

Code:

  exports.checkOrderStatus = functions.database.ref("/RestaurantOrders").onUpdate(async (change, context) => {
        
            var orderStatus = change.after.val().order_status;
        
            if (orderStatus == "accepted") {
         code...
        
        } else {

        return 
    
    }

    }

            var orderStatus = change.after.val().order_status;
        
            if (orderStatus == "accepted") {
         code...
        
        } else {

        return 
    
    }
