Im still getting the same error

PHP Notice: Undefined variable: faker in /firstproject/database/factories/ArticleFactory.php on line 29 PHP Notice: Trying to get property 'sentence' of non-object in /firstproject/database/factories/ArticleFactory.php on line 29 PHP Notice: Undefined variable: faker in /firstproject/database/factories/ArticleFactory.php on line 30 PHP Notice: Trying to get property 'sentence' of non-object in /firstproject/database/factories/ArticleFactory.php on line 30 PHP Notice: Undefined variable: faker in /firstproject/database/factories/ArticleFactory.php on line 31 PHP Notice: Trying to get property 'paragraph' of non-object in /firstproject/database/factories/ArticleFactory.php on line 31

Here is my code:

<?php

namespace Database\Factories;

use App\Models\Article;
use App\Models\User;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;



class ArticleFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Article::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'user_id' => User::factory(),
            'title' => $this->faker->sentence,
            'excerpt' => $this->faker->sentence,
            'body' => $this->faker->paragraph
        ];
    }
}

Running Article::factory()->create() creates a new user in the db, but it appears that the faker parameters are returning null and preventing me from creating a new article as well.
