In Express JS, post() method is working perfectly in firebase cloud function after deploying but not working in local machine

Question

I have one post() and get() request in Express JS. My post() request is not working in local machine.It is throwing 404 error and message "Cannot POST /sendMessages/" .However, when I deploy the app to the firebase cloud function and tested the requests both are working perfect. So, every time when I made changes I had to deploy and then test which is a tedious task.

    const functions = require("firebase-functions");    
    const express = require('express');
    var bodyParser = require('body-parser');
    var cors = require('cors')
    const PORT = 3000;
    const app = express()
app.use(express.json())

app.use(cors())

app.get('/hello', (req, res, next) => {
    res.send('Welcome')
})

app.post('/sendMessages', (req, res) => {

    console.log(req.body)
res.json({ 'status': 'Success' })
})

app.listen(PORT, () => {
    console.log("Server is running on port, " + PORT)
})

exports.app = functions.https.onRequest(app)

Can anyone please tell me what's the issue. Thanks in advance.

Finally, I figured out what silly mistake I have been doing all these days. I was running my nodemon start on normal folder rather than functions folder.
