Express API wont take any requests from POSTMAN

Question

I have been trying to develop an API for use in a MEAN stack application. The API handles user registration and authentication. What's been really funny is that it has not been taking any requests from Postman. Even a simple '/' get request with a response will not work. The error I get on postman is as below

My index.js is as below:

const exp = require('express');
const bp = require('body-parser');
const { success, error } = require('consola')
const { connect } = require('mongoose');

// Bring in the app constants
const { DB, PORT } = require("./config");

// Initialize the application
const app = exp();

// Call the middleware
app.use(cors());
app.use(bp.json);

// User Router Middleware
app.use("/api/users", require("./routes/users"));
app.use("/basic", require("./routes/basic"));

// Connect to the database

const startApp = async () => {
    try {
      // Connection With DB
      await connect(DB, {
        useFindAndModify: true,
        useUnifiedTopology: true,
        useNewUrlParser: true
      });
  
      success({
        message: `Successfully connected with the Database \n${DB}`,
        badge: true
      });
  
      // Start Listenting for the server on PORT
      app.listen(PORT, () =>
        success({ message: `Server started on PORT ${PORT}`, badge: true })
      );
    } catch (err) {
      error({
        message: `Unable to connect with Database \n${err}`,
        badge: true
      });
      startApp();
    }
  };



startApp();

My basic routing is as follows, it itself will not even work for me:

router.get('/', function (req, res) {
    res.send('Hello World!' + req.body)
  })

module.exports = router;

The postman response is as in the screenshot below:

The server does appear to be running but is just refusing all requests it seems.

mongodb://localhost:27017/node-auth


 SUCCESS  Server started on PORT 3000                                                 16:26:36

My apologies.

I was missing a () brace which was allowing the application to run but not correctly. Sometimes all it takes is another eye.

Before: app.use(bp.json); After: app.use(bp.json());

Working perfectly now.
