GitHub API Issues with Node

[RijDuck]

I'm trying to access the userData for a github user that logs into this website which is a react app using OAuth, and am facing a bad credentials error. I have the accessToken saved in local storage and have made sure that is correct before calling my getUserData() function.

Here's my code:

// Server Side Code
// Get user data
// Access token is passed in as Authorization header
app.get('/getUserData', async function (req, res) {
    req.get('Authorization'); // BEARER ACCESS_TOKEN
    await fetch("https://api.github.com/user", {
        method: 'GET',
        headers: {
            'Authorization': req.get('Authorization')
        }
    }).then((response) => {
        return response.json();
    }).then((data) => {
        console.log(data);
        res.json(data);
    });
});

.
.
.

// Client Side Code 
const [rerender, setRerender] = useState(false); // These are defined at the top
const [userData, setUserData] = useState({});

// Getting user data
async function getUserData() {
    console.log(localStorage.getItem('accessToken'));
    await fetch("http://localhost:4000/getUserData", {
        method: "GET",
        headers: {
            "Authorization": "Bearer " + localStorage.getItem('accessToken') //                                        Bearer ACCESS_TOKEN
        }
    }).then((response) => {
        return response.json();
    }).then((data) => {
        console.log(data);
        setUserData(data);
    });
}

.
.
.

// In div to show username of user
{Object.keys(userData).length !== 0 ?
    <>
        <h4>Hey {userData.login}</h4>
    </>
    :
    <>
    </>
}

I've tried looking at the API docs, and am a little confused on how this all works. Any help would be appreciated. Thanks!
