Symfony 4 динамика c выберите страну, выпадающий список города

Question

Привет всем, у меня есть проблема с выбором 3 раскрывающихся списков ввода. У меня есть страна, в стране - штат, а в штате - город. Мне удалось выбрать отображение страны и состояния, но проблема в том, чтобы получить город из штата. Я получил эту ошибку. Идентификатор идентификатора отсутствует для запроса App \ Entity \ CountryState

Здесь находится мой конструктор форм

И на Twig у меня есть это Javascript

var $post_country = $('#create_business_form_country');
    var $post_token = $('#create_business_form__token');

    // Country on change
    $post_country.change(function() {

        $("#create_business_form_state").select2();

        var $form = $(this).closest('form');

        var data = {};

        data[$post_token.attr('name')] = $post_token.val();
        data[$post_country.attr('name')] = $post_country.val();

        $('#create_business_form_state').prop('disabled', true);

        // Replace Old State form to New
        $.ajax({
            url: $form.attr('action'),
            type: $form.attr('method'),
            data: data,
            success: function (html) { 
                
                // Replace current states field ...
                $('#create_business_form_state').replaceWith(
                    // ... with the returned one from the AJAX response.
                        $(html).find('#create_business_form_state')
                );
                
                // Enable Input
                $('#create_business_form_state').prop('disabled', false);
                // Update Select2
                $('#create_business_form_state').select2();
            }
        });
    });

Любое решение по этому поводу, пожалуйста, я пытаюсь погуглить, но решения не получаю. Кто угодно, пожалуйста.
