get method of js-cookie return undefined

Question

Now I'm using js-cookie to store token in cookie and I meet some problems that I can not get token by Cookies.get method, get method is defined as below:

import Cookies from 'js-cookie'

class CookieService {
  get(key: string) {
    return Cookies.get(key);
  }

  set(key: string, value: string, options: object) {
    Cookies.set(key, value, options);
  }

  remove(key: string) {
    Cookies.remove(key);
  }
}

export default new CookieService();

And using it:

import CookieService from "../../services/CookieService";
...
const token = CookieService.get('accessToken');
console.log(token)

I'm going to show how I set token (response.accessToken is token string), it work correctly:

const options = { path: "/"};
CookieService.set("accessToken", response.accessToken, options);
return true;

And when I use get method, it always return undefined (in nextjs + typescript). But It still shows value of token in console of browser:
