Always get exception when login with JWT Management Session

I try to learn how to manage session with JWT. But now I’m stuck because i always get exception after login, and it always redirect me to login page again and again.

There is no error detected, and i can’t find what’s wrong in my code. So i hope you all can help me although it is just look like a simple questions

I try to browse to check where is the problem. And i’m sure the problem is in the file session.php. But i don’t know whats wrong

<?php

// use FirebaseJWTJWT;

class Session
{
    public $username, $role;
    public function __construct(string $username, string $role)
    {
        $this->username = $username;
        $this->role = $role;
    }

}

class SessionManager
{

    // public $SECRET_KEY = 'ajfhakjdfhah/A203FHkafhiuefhhncueuvuwevwevwev';

    public static function login(string $username, string $password): bool
    {
        if ($username == "eko" && $password == "eko") {

            $SECRET_KEY = 'AKDJHFEVN123akdhfvbuevmkc';
            $payload = [
                "username" => $username,
                "role" => "customer"
            ];

            $jwt = FirebaseJWTJWT::encode($payload, $SECRET_KEY, 'HS256');
            setcookie('USER-SESSION', $jwt);
            
            return true;
        } else {
            return false;
        }
    }

    public static function getCurrentSession(): Session
    {
            
        if ($_COOKIE['USER-SESSION']) {
            $jwt = $_COOKIE['USER-SESSION'];
            $SECRET_KEY = 'AKDJHFEVN123akdhfvbuevmkc';
            $payload = FirebaseJWTJWT::decode($jwt, $SECRET_KEY, ['HS256']);
            try {
                $payload = FirebaseJWTJWT::decode($jwt, $SECRET_KEY, ['HS256']);

                return new Session($payload->username, $payload->role);                
            } catch (Exception $exception) {
                throw new Exception("User is not login");                
            }
            
        } else {
            throw new Exception("User is not login");
        }
    }

}
