Modal window does not work on pages, what should I do?

    Hello everyone! I'm a newbie.
    Faced a problem:
    The modal only works on one page per click (I have a site of four pages). Moreover, if you place several buttons on this page, then they will all work and open a window.
    Js code:
    const modalTrigers = document.querySelectorAll('button[data-modal]');
        const modal = document.querySelector('.modal');
        const modalCloseBtn = document.querySelector('[data-close]');
        modalTrigers.forEach(item => {
          item.addEventListener('click', () => {
   = "hidden";
        modalCloseBtn.addEventListener('click', () => {
 = "";

    Below the footer on each page is the following code (modal):
    <div class="modal">
        <div class="modal__dialog">
            <div class="modal__content">
                <form action="#">
                    <div data-close class="modal__close">&times;</div>
                    <div class="modal__title">Мы свяжемся с вами как можно быстрее!</div>
                    <input required placeholder="Ваше имя" name="name" type="text" class="modal__input">
                    <input required placeholder="Ваш номер телефона" name="phone" type="phone" class="modal__input">
                    <button class="btn btn_dark btn_min">Перезвонить мне</button>

    On other pages, it gives the following error:
    jquery.min.js:2 jQuery.Deferred exception: Cannot read property 'addEventListener' of null TypeError: Cannot read property 'addEventListener' of null

    As the error says.

    TypeError: Cannot read property 'addEventListener' of null

    If it works on one page but not on the other, look for differences between them. I am sure somewhere you either did not insert an element or an attribute, or you connect the script differently.

To place the code, please use CodePen or similar tool. Thanks you!
