i m trying to run pjax with express my codes are as following

app.js

var express = require('express');
var path = require('path');

var logger = require('morgan');
var chalk = require('chalk');

var app = express();

var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ parameterLimit: 100000, limit: '50mb', extended: true }));

var config = require('config');
const port = config.get('server.port');

// view engine setup
app.use(pjax());
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');

app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', indexRouter);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
    next(createError(404));
});

// error handler
app.use(function(err, req, res, next) {
    // set locals, only providing error in development
    res.locals.message = err.message;
    res.locals.error = req.app.get('env') === 'development' ? err : {};

    // render the error page
    res.status(err.status || 500);
    res.render('error');
});
//run cmds
console.log(chalk.blue('Exec cmds being run'));
const { exec } = require("child_process");
exec("node bot.js", (error, data, getter) => {
    if (error) {
        console.log("error", error.message);
        return;
    }
    if (getter) {
        console.log("Bot:", data);
        return;
    }
    console.log("Bot started:", data);

});

console.log(chalk.blue.green.underline('panel started at:'), port);
