Laravel API - Argument 1 passed to TokenGuard::__construct() must implement interface UserProvider

REST-API in Laravel 8 using API Authentication.

Introduction

I have Analytics Model Authenticable to authenticate the request in web rather than using default User Model with corresponding analytics and user table table. I have migrated api_token field in analytics table. However, I'm getting below error in response while accessing the API route in POSTMAN.

Response

{
"message": "Argument 1 passed to Illuminate\\Auth\\TokenGuard::__construct() must implement interface Illuminate\\Contracts\\Auth\\UserProvider, null given, called in source\\vendor\\laravel\\framework\\src\\Illuminate\\Auth\\AuthManager.php on line 162",
"exception": "TypeError",
}

source\vendor\laravel\framework\src\Illuminate\Auth\AuthManager.php on line 162

    public function createTokenDriver($name, $config)
    {
        $guard = new TokenGuard(
            $this->createUserProvider($config['provider'] ?? null),
            $this->app['request'],
            $config['input_key'] ?? 'api_token',
            $config['storage_key'] ?? 'api_token',
            $config['hash'] ?? false  // **** This is line 162 **** //
        );

I tried changing line 162 as $config['hash'] ?? true but still getting same error.

Note: The Analytics and User Model are Authenticable. While I have the api_token field in the analytics table

Request:

I'm sending GET instance of HTTP Request on endpoint http://example.com/api/user?api_token=token(this is unhashed token)

Below is the following configuration.

route/api.php

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});

The Analytics and User Model are follow:

<?php

namespace App;
use Illuminate\Notifications\Notifiable;
use Notification;
use Illuminate\Foundation\Auth\User as Authenticatable;
use App\Notifications\AnalyticsResetPassword;
use Illuminate\Database\Eloquent\Model;

class Analytics extends Authenticatable
{
    use Notifiable;
    public function sendPasswordResetNotification($token)
    {
        $this->notify(new AnalyticsResetPassword($token));
    }

    protected $table = "analytics";

    protected $fillable = ['name', 'email', 'password', 'mobile', api_token', ];

    protected $hidden = ['password', 'api_token', 'remember_token', ];
}

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

    protected $fillable = ['name', 'email', 'password', ];

    protected $hidden = ['password', 'remember_token',];

    protected $casts = ['email_verified_at' => 'datetime',];
}

The guard and provider array in config/auth.php configuration file:

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

        'analytics' => [
            'driver' => 'session',
            'provider' => 'analytics',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'user',
            'hash' => true,
        ],
    ],

    'providers' => [

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

        'analytics' => [
            'driver' => 'eloquent',
            'model' => App\Analytics::class,
        ],
    ],

The token generating method in Controller

    public function token(Request $request)
    {
        $token = Str::random(60);
        $user = Auth::user();
        $user->api_token = hash('sha256', $token);
        $user->save();
        return redirect('/analytics/security')->with('success', 'Token Generated Successfully!')->with("token" , $token);
    }
