I'm trying to build a nodeapi for which I am using bunch of libs like express, morgan, nodemon.
Everything was correctly installed with no error in installation and when I try to use nodemon by updating in package.json file it work for one time then it shooting [is showing? reporting? an] unexpected error

here the error on terminal

> node@1.0.0 start /root/Downloads/node
> nodemon server.js

[nodemon] 2.0.7
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*

}
[nodemon] app crashed - waiting for file changes before starting...

Here's My app.js looks like

const express = require('express');
const app = express();
const morgan =require('morgan')

const employeeRoutes =require('./api/routes/employee');
const departmentRoutes =require('./api/routes/department');

app.use(morgan('dev'));

// Routes for api 
app.use('/employee',employeeRoutes);
app.use('/department',departmentRoutes);

module.exports = app;

And here is my server.js

const http=require('http');
const app =require('./app');

const port =process.env.PORT || 3000;

const server = http.createServer(app);

server.listen(port);

console.log('Server Has Been Started');
console.log('localhost:'+port);

I am using postman to access all request and response.

I did try using npm cache clean --force but it's not working anymore.

Experienced something like this before, just try rebooting your system that should fix the issue
