Laravel 5.2 Session flash not working even with web middleware

Question

I am trying to implement flash messaging using sessions but am unable to do so.

In my controller I have:

public function store(Request $request) {
    session()->flash('donald', 'duck');
    session()->put('mickey', 'mouse');
    return redirect()->action('CustomerController@index')->with('bugs', 'bunny');
}

But when I check the session variables in the view, I can only see the values from session()->put('mickey', 'mouse').

Session:

{"_token":"F6DoffOFb17B36eEJQruxvPe0ra1CbyJiaooDn3F","_previous":{"url":"http:\/\/localhost\/customers\/create"},"flash":{"old":[],"new":[]},"mickey":"mouse"}

A lot of people encountered this problem by not having the relevant routes inside the web middleware. I made sure to do this as well but it still wouldn't work.

In routes.php:

Route::group(['middleware' => ['web']], function () {

    Route::get('/', function () {
        return view('welcome');
    });

    Route::get('/customers', 'CustomerController@index');
    Route::get('/customers/create', 'CustomerController@create');
    Route::post('/customers', 'CustomerController@store');
});

In Kernel.php:

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
    ],

    'api' => [
        'throttle:60,1',
    ],
];

Can anyone let me know what I could be doing wrong here? Thanks!

Fixed the issue by replacing

Route::group(['middleware' => ['web']], function () {
   ...
});

with

Route::group(['middlewareGroups' => ['web']], function () {
   ...
});

No idea why this works though when all the documentation suggests that we use ['middleware' => ['web']]
