Getting Email query from server site, It's not connecting to my client site But it's working on my server site

app.get('/login', async (req, res) => {
    const user = req.body;
    const accessToken = jwt.sign(user, process.env.ACCESS_TOKEN_SECRET, {
        expiresIn: '1d'
    });
    res.send({ accessToken });
});

const Login = () => {
    const navigate = useNavigate();

    const [signInWithEmailAndPassword, loading, error] = useSignInWithEmailAndPassword(auth);
    const [user] = useAuthState(auth);
    if (user) {
        navigate('/');
    }

    const handleLogin = async e => {
        alert('ok');

        e.preventDefault();
        const email = e.target.email.value;
        const password = e.target.password.value;
