Too few arguments to function Database\Seeders\DatabaseSeeder::Database\Seeders\{closure}()

Question

I want to test my database and I have made factories and the following is my code inside my seeder file

public function run()
{
    Category::factory()->count(10)->create();

    User::factory()
        ->has(Profile::factory()->state(function (array $attributes, User $user) {
            return ['user_id' => $user->id];
        }))
        ->has(Post::factory()->count(50)
            ->state(function (array $attributes, User $user, Category $category) {
            return ['user_id' => $user->id, 'category_id' => $category->id];
        })
        ->has(Comment::factory()->count(3))
            ->state(function (array $attributes, User $user, Post $post) {
            return ['user_id' => $user->id, 'category_id' => $post->id];
        }))
        ->create();


}

I want to make some categories and 1 or more users with attached profiles, posts and comments. Can someone please check if my code is correct because it is giving the following error:

There is a problem with your second and third closure:

->state(function (array $attributes, User $user, Category $category)

You cannot expect more than $attributes and created parent model ($user in this case). This $category parameter causes the problem, you need to acquire this object outside closure.
