JWT token returning undefined in MERN application

I am using JWT token for authentication in my MERN app. when i click on this endpoint "http://127.0.0.1:1000/api/v1/users/login" in postman to login a user and this endpoint "http://127.0.0.1:1000/api/v1/users/verify" to verify a user's token, the token is returned. However, when i do the same operation in my react frontend app, the token returns undefined. Please what am i doing wrong? Here is my React code. P.S the token is stored in the cookies.
function Welcome() {
const [user, setUser] = useState("");
const sendRequest = async () => {
const res = await axios
.get("http://127.0.0.1:1000/api/v1/users/verify", {
withCredentials: true,
})
.catch((err) => console.log(err));
const data = await res.data;
console.log("RESPONSE", data);
return data;
};
React.useEffect(() => {
sendRequest().then((data) => console.log(data));
}, []);
console.log(user);
return <div>Welcome</div>;
}
Here is the Verify token code in my express app
exports.verifyToken = async (req, res, next) => {
const cookies = await req.headers.cookie;
const token = cookies.split("=")[1];
if (!token) {
res.status(404).json({ message: "no token found" });
}
jwt.verify(String(token), process.env.JWT_SECRET, (err, user) => {
if (err) {
return res.status(400).json({message: "Invalid token" });
}
req.id = user.id;
});
next();
};

User cookie parser
const express = require("express");
const app = express();
const cookieParser = require("cookie-parser");
app.use(express.json());
app.use(cookieParser());
app.get("/", (req, res) => {
res.setHeader("Set-Cookie", "name=langesh;SameSite=None;");
res.send("hello");
});
app.get("/get-cookie", (req, res) => {
res.send(req.cookies);
});
app.listen(9000);
output
{name : "langesh"}

I personally don't have much experience with axios, I prefer fetch() method, it works perfectly.
That said, I think this issue could arise because token isn't identified in the request. Try adding headers: { Authorization: `Bearer ${token}`} to your get method and see if it is fixed.
Your code should look like :
axios.get("http://127.0.0.1:1000/api/v1/users/verify", {
headers: {
Authorization: `Bearer ${token}`
},
withCredentials: true,
})

Trying to fetch the google api's book

Since yesterday I'm trying to get the books on the google API for an exercise, I had to pass on a lot of errors and here is my final code, from this moment I can't move forward:
export async function fetchGoogle (url, options = {}) {
const headers = {Accept : 'application/json', ...options.headers}
const r = await fetch(url, {...options, headers})
if (r.ok) {
return r.json()
}
throw new Error ('Error server', {cause :r})
}
// Bypass error 200
var express = require('express')
var cors = require('cors')
var app = express()
var corsOptions = {
origin: 'http://example.com',
optionsSuccessStatus: 200 // some legacy browsers (IE11, various SmartTVs) choke on 204
}
app.get('/products/:id', cors(corsOptions), function (req, res, next) {
res.json({msg: 'This is CORS-enabled for only example.com.'})
})
app.listen(80, function () {
console.log('CORS-enabled web server listening on port 80')
})
Then I import this into my main script :
import { fetchGoogle } from "./api.js"
const books = await fetchGoogle ('https://www.googleapis.com/auth/books')
console.log(books)
After all these fights I get the error : Uncaught ReferenceError: require is not defined
at api.js:12:15
Thanks in advance for helping

Mainly this issue occurs if the scopes are not added in your App registration. Please make sure that it is added to correct app registration and permission is granted by an admin.
Please follow this link to call an API using MSAL -
Acquire token.
For you further reference we are adding a sample link where we are using MSAL flow to call Graph.
https://github.com/OfficeDev/Microsoft-Teams-Samples/blob/v-nikija/tab-sso-obo-update/samples/tab-sso/nodejs/src/server/tabs.js
Please refer above sample and in authority can you specify the tenantId -
authority: "https://login.microsoftonline.com/${your_tenant_Id}".

Google Drive OAuth 2.0 Invalid grant_type

Following the example from OAuth2WebServer from google I'm trying to set up an authentication flow from an express app using the HTTP/REST method they have but with every request I am returned with an error
I went through Google OAuth “invalid_grant” nightmare — and how to fix it but unfortunately it did not help.
{
error: "unsupported_grant_type",
error_description: "Invalid grant_type: "
}
This is a shortened version of the error I am receiving. If you need to see more of the error let me know and I can post it.

Using Node Twitter to send a tweet, twitter api 401 error

I'm using node and express to access the twitter api. the following code gives me a 401 error. I've tried changing my apps access to read, write and access, and regenerating my api keys, but that still gives me an error saying that it can't authenticate me. I read on the twitter forums that leaving the url callback field in the api app settings might be causing this, but that didn't fix it either.
const port = (process.env.VCAP_APP_PORT || 3000);
const express = require("express");
const twitter = require('twitter');
const app = express();
const twitterClient = new twitter({
consumer_key: 'key',
consumer_secret: 'key',
access_token_key: 'key-key',
access_token_secret: 'key'
});
app.get('/hello', (req, res) => {
twitterClient.stream('statuses/filter', {track: 'javascript'}, function(stream) {
stream.on('data', function(event) {
console.log(event && event.text);
});
stream.on('error', function(error) {
throw error;
});
});
});
