getting following error when using socialite authenticate facebook. using laravel 5.2 , first time trying implement socialite. ideas ?

fatalerrorexception in abstractprovider.php line 134: call member function set() on non-object 

route :-

route::get('/login', 'authcontroller@login'); 

authcontroller.php :-

<?php namespace app\http\controllers; use illuminate\http\request; use app\http\requests; use app\http\controllers\controller;  class authcontroller extends controller { public function login() {   return \socialite::with('facebook')->redirect(); } } 

services.php setup follows details in .env file :-

'facebook' => [     'client_id'     => env('facebook_client_id'),     'client_secret' => env('facebook_client_secret'),     'redirect'      => env('facebook_redirect'), ], 

the same error reported here no response :- https://laracasts.com/discuss/channels/laravel/laravel-socialite-session-errors-in-52/replies/125233

had same problem...

found answer here: in routes.php, did define routes inside web middleware group? seems common problem 5.2 upgrades :)

it looks have put routes in middleware because includes session creation needed in abstractprovider.php 134

$this->request->getsession()->set('state', $state = str::random(40)); 

this how code routes.php looks (and works):

    <?php  /* |-------------------------------------------------------------------------- | routes file |-------------------------------------------------------------------------- | | here register of routes in application. | it's breeze. tell laravel uris should respond | , give controller call when uri requested. | */  route::get('/', function () {     return view('welcome'); });  route::get('admin', function () {     return view('admin_template'); });  route::get('test', 'testcontroller@index');   /* |-------------------------------------------------------------------------- | application routes |-------------------------------------------------------------------------- | | route group applies "web" middleware group every route | contains. "web" middleware group defined in http | kernel , includes session state, csrf protection, , more. | */  route::group(['middleware' => ['web']], function () {     //     route::get('auth/google', 'auth\authcontroller@redirecttoprovider');     route::get('auth/google/callback', 'auth\authcontroller@handleprovidercallback');  });
