laravel 5.8 and launch request and even intent is always 404

[gigamike]

Hi,

im using laravel 5.8 and launch request and even intent is always 404. Im sure i follow the correct installation i.e.

config/app.php
'providers' => [
\Develpr\AlexaApp\Provider\LaravelServiceProvider::class,
],

'aliases' => [
'AlexaRoute' => \Develpr\AlexaApp\Facades\AlexaRouter::class,
'Alexa' => \Develpr\AlexaApp\Facades\Alexa::class,
],

routes/web.php
AlexaRoute::launch('/alexa', 'App\Http\Controllers\AlexaController@launch');

AlexaRoute::sessionEnded('/alexa', function() {
return '{"version":"1.0","response":{"shouldEndSession":true}}';
});

AlexaRoute::intent('/alexa', 'HelloWorldIntent', 'App\Http\Controllers\AlexaController@helloWorldIntent');

app/Http/Controllers/AlexaController.php
namespace App\Http\Controllers;

use Illuminate\Http\Request;

use Alexa;

class AlexaController extends Controller
{
public function launch(){
return Alexa::say("This is launch intent");
}

public function helloWorldIntent(){
  return Alexa::say("This is hello world intent");
}

}

What am i missing?

Thanks in advance
