Express JS route with POST request returns 404 Cannot GET error in Postman

Question

I am creating APIs in Nodejs using express and body-parser. I am able to successfully make the GET requests using postman but when using POST request it always throws error 404 not found Cannot GET /

Express Version :@4.17.1
Body Parser Version: @1.19.0

Please check the code below

server.js file

require('dotenv').config();
const express = require("express");
const http = require("http");

var addRequestId = require('express-request-id')();
const requestIp = require('request-ip');
const cron = require("node-cron");
const cluster = require('cluster');
const os = require('os');
const v1 = require('./routes/v1');
const jobs = require('./routes/jobs/sync_job');
const bodyParser = require("body-parser");

// Check if current process is master.
if (cluster.isMaster) {

  // Get total CPU cores.
  const cpuCount = os.cpus().length;

  // Spawn a worker for every core.
  for (let j = 0; j < cpuCount; j++) {
    cluster.fork();
  }



  var port = parseInt(3000);
  var app = express();

  var server = http.createServer(app);
  app.use(addRequestId);
  app.use(requestIp.mw())
  app.use(bodyParser.json({limit: '50mb'}));
  app.use(bodyParser.urlencoded({limit: '50mb', extended: false}));
  server.listen(port, () => { })
  console.log("SERVER UP AND RUNNING");

  app.use('/v1/jp', require('./routes/report_center'));



}


cluster.on('exit', function (worker) {
  console.log(`Worker ${worker.id} died'`);
  console.log(`Staring a new one...`);
  cluster.fork();
});

report_center.js

const moment = require('moment');
const express = require('express');
const bodyParser = require("body-parser");
const reports = express.Router();

const mysql = require('mysql');
const async = require("async");
const constants = require('./v1/constant.js');
var _ = require('lodash');


var pool = mysql.createPool({
    connectionLimit: 1000,
    host: process.env.DB_HOST,
    port: process.env.DB_PORT,
    user: process.env.DB_USER,
