[request entity too large error when using oas3-tools package,openapi 3.0 in node.js]

index.js file

'use strict';

var path = require('path');
var http = require('http');
var cors = require('cors');

var expressAppConfig = oas3Tools.expressAppConfig(

  expressAppConfig.addValidator();
  var app = expressAppConfig.getApp();

  app.use(cors());
  var json2xls = require('json2xls');

// Initialize the Swagger middleware
http.createServer(app).listen(serverPort, function () {

// Connect to database 
var mongo = require("./utils/db");

PFB the version of the tools which we've used. "express": "^4.17.1", "oas3-tools": "2.1.3"

I've tried body-parser and app.use(express.json({limit:'25mb'})). But nothing resolved the request entity too large error. It would be great if anyone suggest me any different solution.
