Double slider Sign in/up Form

Question

Всем привет. Начал вникать в react, но никак не пойму, что не так с формой.

Пишу форму авторизации, двойную, но при инициализации возникает ошибка:

Cannot read properties of null (reading 'addEventListener') TypeError: Cannot read properties of null (reading 'addEventListener')

Подскажите, что не так?

Как то не так определяю функцию, ток не пойму ,что не так.

Буду благодарен за помощь.

const signUpButton = document.getElementById('signUp');
const signInButton = document.getElementById('signIn');
const container = document.getElementById('container');

signUpButton.addEventListener('click', () => {
    container.classList.add("right-panel-active");
});

signInButton.addEventListener('click', () => {
    container.classList.remove("right-panel-active");
});
