I am running an express server that has some REST API endpoints including authentication endpoint: http://localhost:3000/login using jwt (json web token), the server run but when I used postman and several other methods to call the endpoint I keep waiting for the results.

I created an express server in the nodejs environment like so :

require("dotenv").config()
const express = require('express')
const app = express()
const jwt = require('jsonwebtoken')
app.use(express.json)


const posts = [
    {
        username: "kyle",
        name: "post1"
    },
    {
        username: "Tyler",
        name: "post2"
    },
]

const authenticateToken = (request, response, next) => {
    const authHeader = request.headers['authorization']
    const token = authHeader && authHeader.split(' ')[1]

    if(token === null) { return response.sendStatus(401)}

    jwt.verify(token , process.env.ACCESS_TOKEN_SECRET_KEY, (err, user) => {
        if(err) return response.sendStatus(403)

        request.user = user
        next()
    })


}

app.get("/posts", authenticateToken, (request, response) => {

    const filteredPosts = posts.filter(post => post.username === request.user.username)

    response.json(filteredPosts)
})

app.post("/login", (request, response) => {
    //authenticate the user

    const username = request.body.username

    const user = {username: username}
    const accessToken = jwt.sign(user, process.env.ACCESS_TOKEN_KEY)
    response.json({accessToken: accessToken})

})



app.listen(3000, () => {
    console.log(`app is lestening on port: 3000`)
})

I run the server successfully using the command : node server.js

and use postman like so :
postman dashboard where the call is made

I expected the request to be treated and I will have the access token as a response, but the request kept pending, I tried using multiple ways to call the api endpoint and I tried to update the nodejs version and creating another project but this didn’t work

the rest client vscode approach

here is my package.json file:
