This is the change I made in the completed food Tracker for my comment:

router.get("/foodtracker") { request, response, next in
    defer {
        next()
    }
}

2. Build a JSON string description of the FoodTracker meal store. Add the following code inside your “/foodtracker" route below the defer closure:

   Meal.findAll { (result: [Meal]?, error: RequestError?) in
   guard let meals = result else {
       return
   }
   var allMeals: [String: [[String:Any]]] = ["meals" :[]]
   for meal in meals {
       allMeals["meals"]?.append(["name": meal.name, "rating": meal.rating])
   }
   }

3. Render the template and add it to your response. Add the following line after the for meal in meals loop:
