How to apply middleware in node js app.post

I'm trying to apply this middleware variable into my post request in my website, it is supposed to console log the id of the user but it returns undefined, could you please help me with this issue? If I'm applying the middleware incorrectly or something like that?

middleware

export const requireSignin = jwt({
  secret: process.env.JWT_SECRET,
  algorithms: ["HS256"],
});

Controller

export const createConnectAccount = async (req, res) => {
    console.log('REQ USER FROM REQUIRE_SIGNIN MIDDLEARE', req.user)
    console.log('YOU HIT CREATE CONNECT ACCOUNT ENDPOINT')
}

import express from 'express'



const router = express.Router()

//Controllers

import express from 'express'
import { requireSignin } from '../middlewares'


const router = express.Router()

//Controllers

import { createConnectAccount} from '../controllers/stripe'

router.post('/create-connect-account',requireSignin, createConnectAccount)


module.exports = router
