422 Unprocessable Entity with Laravel 8 delete route - php

Question

I have a common Larvel 8 project with this codes:
In the routes/api.php file:
Route::resources([
'menu/menu' => Menu\MenuController::class,
]);
In the app/Http/Controllers/Menu/MenuController.php file:
public function destroy(DestroyMenuRequest $request, Menu $menu) {
$menu->delete();
return Response::HTTP_OK;
}
In the DestroyMenuRequest.php file:
class DestroyMenuRequest extends FormRequest {
public function authorize() {
return $this->user()->can('destroy.menu');
}
public function rules() {
return [
'id' => 'required|integer|exists:menus,id',
];
}
}
Then I send a DELETE HTTP request to the url {{domain}}/api/menu/menu/2 and I get back this:
In header 422 (Unprocessable entry), and in the body:
{
"message": "The given data was invalid.",
"errors": {
"id": [
"The id field is required."
]
}
}
If I list routes with php artisan r:l I see the route with the right controller:
DELETE | api/menu/menu/{menu} | menu.destroy | App\Http\Controllers\Menu\MenuController#destroy | api auth:api
Any idea what is the solution?
Thanks!

As the comment above me pointed out, you are generating routes for resource controller.
In your routes list, you can see that the route does not expect an actual ID as the parameter, but rather it expects Menu model instance from which Laravel will automatically grab the ID.
Example if you are submitting a form:
<form method="POST" action="{{ route('menu.destroy', ['menu' => $menuObject]) }}">
#method("DELETE")
...
</form>
Where $menuObject is of type Models\Menu. In other words, it's an instance of Menu model you have created
