angular - sessionStorage works but localStorage gets JSON.parse error, what's the difference?

Question

The following code works if I make a single change: replacing localStorage with sessionStorage.

Can someone explain why? To my knowledge, they are identical in functionality and differ only in that sessionStorage is limited to a tab.

  read(key: string): any {
    const item = localStorage.getItem(key);
    return JSON.parse(item);
  }

  write(key: string, value: any): void {
    localStorage.setItem(`${key}`, JSON.stringify(value));
  }
