Проверка не возвращает ошибки Laravel 7

Question

Я пытался проверить поля ввода в проекте, над которым я работаю. Он не возвращал ошибки проверки. Также каждый раз, когда я удаляю проверку и пытаюсь отправить данные формы после ее заполнения, она возвращает неопределенную ошибку индекса.

Это мой контроллер

Попробуйте следующее

use use Illuminate\Support\Facades\Validator;
//...
$validator = Validator::make($request->all(), [
     'category_id' => 'required',
     ...
]);

if ($validator->fails()) {
     return redirect()->back()
         ->withErrors($validator)
         ->withInput();
}

$data = $validator->validated();
