there issuse in my code it does fetch from database which found an authorized but it is authorized data error is JsonWebTokenError: jwt malformed

here the requireAuth component

const jwt = require('jsonwebtoken');
const User = require('../Model/userModel');

const requireAuth = async (req, res, next) => {
    const { authorization } = req.headers;

    if (!authorization) {
        return res.status(401).json({ error: 'Authorization required' });
    }

    const token = authorization.split(' ')[1];

    try {

        const { _id } = jwt.verify(token, process.env.SECRETE);
        req.user = await User.findOne({ _id }).select('_id');
        if (!req.user) {
            return res.status(401).json({ error: 'User not found' });
        }
        next();
    } catch (error) {
        console.error(error);
        res.status(401).json({ error: 'Request is not authorized' });
    }
};

module.exports = requireAuth;

here the home.js components which has GET METHOD

import { useEffect } from "react";
import Blogs from "../components/Blogs";
import { useBlogContext } from "../Hooks/useBlogContext";
import { useAuthContext } from "../Hooks/useAuthContext";

const Home = () => {
    const { dispatch } = useBlogContext();
    const user = useAuthContext()

    useEffect(() => {
        const fetchBlog = async () => {
            const response = await fetch('/api/blog', {
                method: 'GET',
                headers: {
                    'Content-Type': 'application/json',
                    'authorization': `Bearer ${user.token}`
                }
            });
            const json = await response.json();
            if (response.ok) {
                dispatch({ type: 'SET_BLOGS', payload: json });
            }
        };
        fetchBlog();
    }, [dispatch, user.token]);

    return (
        <div className="Home">
            <div className="Home-container">
                <h1>RetroBlog</h1>
                <p>Where you can create, update, and show ideas</p>
            </div>
            <h1>All Recent Blogs</h1>
            <Blogs />
        </div>
    );
};
export default Home;

I needed it to fetch data correctly from the database
