Why am I getting a 500 error?

Question

Laravel

I don’t understand why my framework throws a 500 error. It worked like this when it was in pure php without a framework, then everything worked fine, but now it doesn’t even reach the getMessage () method
Post request goes using ajax. Previously, there was no csrf token, now it has become, but in principle this is not the point

class LandingController extends Controller
{
public function index(Request $request)
    {
        $validate = new ValidateLanding($request->all());
        return json_decode($validate->getValidate(), JSON_UNESCAPED_UNICODE);
    }
}

In ValidateLanding

namespace Latina;


interface ValidateData
{
    /**
     * Если все верно то сохраняет в бд и отправляют по email лид
     * Проверка на заполнение телефона или email
     * @return array
     */
    public function getValidate();

    /**
     * Выводит сообщение о результате
     * @param bool $error
     * @param string $message
     * @return array
     */
    public function getMessage(bool $error, string $message);
}

class ValidateLanding implements ValidateData
{
    private $name;
    private $phone;
    public $result = [];

    public function __construct(array $data)
    {
        $this->phone = $data['phone'];
        $this->name = $data['name'];
    }

    public function getValidate()
    {
        if (!$this->name && !$this->phone){
            return $this->getMessage(true, 'Заполните имя и телефон');
        } elseif (!$this->name){
            return $this->getMessage(true, 'Заполните имя');
        } elseif (!$this->phone){
            return $this->getMessage(true, 'Заполните телефон');
        } else {
            preg_match('/[\d]+/', $this->name, $matches);
            if (strlen($this->phone) != 16){
                return $this->getMessage(true, 'Некорректный телефон');
            }
            if ($matches[0]){
                return $this->getMessage(true, 'Имя не должна содержать цифры');
            }
            return $this->getMessage(false, 'Сообщение отправлено');
        }
    }


    public function getMessage(bool $error, string $message)
    {
        return $this->result = [
            'error' => $error,
            'message' => $message
        ];
    }
}

The problem is that when it comes to the check line if (!$this->name && !$this->phone){
like And so on, then it simply does not process $this->getMessage and throws out a 500 error. Although the data is there.
Here is a screenshot from the debugger

. I left the name and phone number empty for this check to work, but it goes to return $this->getMessage and an error occurs

Look at the error in the logs...
And no, it's not that mistake.
