I’m trying to setup a jwt authentication on laravel 6 using mongodb and jwt-auth

this is the user class

<?php

namespace App;

use TymonJWTAuthContractsJWTSubject;
use IlluminateContractsAuthMustVerifyEmail;
use IlluminateFoundationAuthUser as Authenticatable;
use IlluminateNotificationsNotifiable;

class User extends Authenticatable implements JWTSubject
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    /**
     * Get the identifier that will be stored in the subject claim of the JWT.
     *
     * @return mixed
     */
    public function getJWTIdentifier()
    {
        return $this->getKey();
    }

    /**
     * Return a key value array, containing any custom claims to be added to the JWT.
     *
     * @return array
     */
    public function getJWTCustomClaims()
    {
        return [];
    }
}

the controller

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;

class AuthController extends Controller
{
    public function __construct()
    {
        $this->middleware('jwt', ['except' => ['login']]);
    }

    /**
     * Get a JWT via given credentials.
     *
     * @return IlluminateHttpJsonResponse
     */
    public function login()
    {
        $credentials = request(['username', 'password']);
        
        if (! $token = auth()->attempt($credentials)) {//here I get an error undefined method attemp
            return response()->json($credentials, 401);
        }

        return $this->respondWithToken($token);
    }

    protected function respondWithToken($token)
    {
        return response()->json([
            'meta' =>[
                "success" => true,
                "errors" =>[]
            ],
            "data" => [
                "token" => $token,
                "minutes_to_expire" => 1440
            ]
        ]);
    }
}

the guards

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

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

    'api' => [
        //'driver' => 'token',
        'driver' => 'jwt',
        'provider' => 'users',
        //'hash' => false,
    ],
],

and I deleted the api prefix

protected function mapApiRoutes()
    {
        Route::middleware('api')
             ->namespace($this->namespace)
             ->group(base_path('routes/api.php'));
    }

and I get this error when I call the /auth route

In this line,I get an error undefined method attemp

if (! $token = auth()->attempt($credentials))

and I dont know how to set the User class to use it as a mongo model using jenssegers/laravel-mongodb
