Laravel: Authentication user provider [] is not defined

Question

I am trying to build a simple website which will have no user management.

I am using the database driver for both cache and sessions.

I have removed all the user-related boilerplate code that Laravel came with, but I keep getting the error message in the title.

This is my config/auth.php:

return [

    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
        ],
    ],

    'providers' => [
        'users' => [],
    ],

    'passwords' => [
        'users' => [],
    ],

];

Is it possible to have no user providers defined if one intends to not support users on his website?

EDIT 1: After disabling the Illuminate\Auth\AuthServiceProvider service provider, I get the following exception:

ReflectionException thrown with message "Class auth.driver does not exist"

Answer 1

You likely need to comment out the AuthServiceProvider in config/app.php:

'providers' => [

    /*
     * Laravel Framework Service Providers...
     */
    Illuminate\Auth\AuthServiceProvider::class,  // COMMENT THIS OUT

If you post your whole stack trace we could confirm where this error is coming from
