Laravel-Mongodb authentication always return false

Question

I'm using my own collection named customer instead of users in this case.

Model

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
// use Illuminate\Database\Eloquent\Model;
use Jenssegers\Mongodb\Eloquent\Model;
use Jenssegers\Mongodb\Auth\User as Authenticatable;

class Customer extends Authenticatable
{
    use HasFactory;

    protected $collection='customer';

    protected $guarded = ['id'];

    public $timestamps = false;

}

Controller

namespace App\Http\Controllers;

use App\Models\Customer;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Str;
use Illuminate\Contracts\Auth\Authenticatable;

class LoginController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view('login', ["title" => "LOGIN"]);
    }

    public function validation(Request $request)
    {
    $credentials = $request->validate([
        'email' => ['required', 'email'],
        'password' => ['required'],
    ]);

    if (Auth::attempt($credentials)) {
        $request->session()->regenerate();

        return redirect()->intended('dashboard');
    }

    return back()->withErrors([
        'email' => 'The provided credentials do not match our records.',
    ])->onlyInput('email');
    }
}

config/auth.php

'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\Models\Customer::class,
],

config/database.php

'mongodb' => [
'driver' => 'mongodb',
'dsn' => env('DB_URI', 'mongodb://localhost:27017'),
'database' => 'herbal66',
],

.env

DB_CONNECTION=mongodb
DB_URI=mongodb://localhost:27017

It always return 'The provided credentials do not match our records.'.
What should i do ?
