Laravel 5.1 adding middleware to resource route - php

Question

so I have been trying to use middleware with my route resource and having trouble making it work.
Here is my routes setup:
Route::group(['prefix' => 'api','middleware' => 'locationRouteValidator'], function()
{
Route::resource('location', 'LocationController');
});
and route seems to be setup properly:
php artisan route:list
+--------+----------+------------------------------+----------------------+-------------------------------------------------+------------------------+
| Domain | Method | URI | Name | Action | Middleware |
+--------+----------+------------------------------+----------------------+-------------------------------------------------+------------------------+
| | GET|HEAD | / | | Closure | |
| | GET|HEAD | api/location | api.location.index | App\Http\Controllers\LocationController#index | locationRouteValidator |
| | POST | api/location | api.location.store | App\Http\Controllers\LocationController#store | locationRouteValidator |
| | GET|HEAD | api/location/create | api.location.create | App\Http\Controllers\LocationController#create | locationRouteValidator |
| | DELETE | api/location/{location} | api.location.destroy | App\Http\Controllers\LocationController#destroy | locationRouteValidator |
| | PATCH | api/location/{location} | | App\Http\Controllers\LocationController#update | locationRouteValidator |
| | GET|HEAD | api/location/{location} | api.location.show | App\Http\Controllers\LocationController#show | locationRouteValidator |
| | PUT | api/location/{location} | api.location.update | App\Http\Controllers\LocationController#update | locationRouteValidator |
| | GET|HEAD | api/location/{location}/edit | api.location.edit | App\Http\Controllers\LocationController#edit | locationRouteValidator |
+--------+----------+------------------------------+----------------------+-------------------------------------------------+------------------------+
so now I create the middleware :
php artisan make:middleware locationRouteValidator
and leave the default code, which is :
public function handle($request, Closure $next)
{
return $next($request);
}
and just for testing, in my controllers show method, I echo out the passed id like so:
public function show($id)
{
//
echo "show ".$id;
}
so now I expect that when I visit /public/api/location/abcd it should display:
show abcd or when I visit /public/api/location/1234 it should display show 1234 after which I intended to modify the middleware to allow only numeric values to be passed into {location}.
But If I just run with the default middleware code, the page returns white without displaying anything. I remove the middleware from the route, and it displays the text as expected.
I know I could attach the middleware to the controller instead, but I thought of attaching it in the route instead so that I could write and apply some common middleware by using the route's group feature, which should be possible, right?
Where do you guys think I am going wrong? Thanks in advance for looking!

Check your \app\http\kernel.php file to see if you have registered the middleware as a route middleware.
