выдает ошибку на переменной  days!

Добрый день ! Возникла проблема  в  timer.js с переменной days ! выдает ошибку   Unresolved variable or type days

const timer = (id, deadline) => {
    const addZero = (num) =>{
        if (num <= 9) {
            return '0' + num;
        }else {
            return num;
        }
    };

    const getTimeRemaining = (endtime) => {
        const t = Date.parse(endtime) - Date.parse(new Date()),
            seconds = Math.floor((t/1000) % 60),
            minutes = Math.floor((t/1000/60) % 60),
            hours = Math.floor((t/(1000 * 60 * 60) % 24),
            days = Math.floor((t/(1000 * 60 * 60 * 24))); // ОШИБКА НА ЭТОЙ СТРОКЕ 



            return {
