Laravel - Illegal offset type in AuthManager.php

Question

I'm trying to use middleware in the laravel routes but when I use the auth middleware the following error shows: https://i.sstatic.net/z6KGb.png in my web.php i have Route::get('/','Pages\GenericPagesController@get_index')->middleware('auth'); in config/auth.php i had to uncomment the providers -> users section because my table name is different than the usual users

    /*
|--------------------------------------------------------------------------
| User Providers
|--------------------------------------------------------------------------
|
| All authentication drivers have a user provider. This defines how the
| users are actually retrieved out of your database or other storage
| mechanisms used by this application to persist your user's data.
|
| If you have multiple user tables or models you may configure multiple
| sources which represent each model / table. These sources may then
| be assigned to any extra authentication guards you have defined.
|
| Supported: "database", "eloquent"
|
*/
'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model' => App\User::class,
    ],
     'users' => [
         'driver' => 'database',
         'table' => 'users',
     ],
],

Answer 1

For people who came here for a solution for lumen :

uncomment the following in bootstrap/app.php

$app->routeMiddleware([
    'auth' => App\Http\Middleware\Authenticate::class
]);  

Answer 2

I think you need to comment the

'users' => [
    'driver' => 'eloquent',
    'model' => App\User::class,
],

The providers now is an array that has the values with same key. If you don't use the eloquent you can comment it or just rename it. Hope this can help. By the way, you might want to check whether your default guard is web or not.
