Throws an error. how to fix?!?!?!?!?

let mongoose = require('./libs/mongoose');
let config = require('./config');
let express = require('express')
let session = require('express-session');
let app = express();
let MongoStore = require('connect-mongo')(express);

app.use(session({
  secret: config.get('session:secret'),
  key: config.get('session:key'),
  cookie: config.get('session:cookie'),
  store: new MongoStore({mongoose_connection: mongoose.connection})
})); 

app.use((err, req, res, next) => {
  req.session.numberOfVisits = req.session.numberOfVisits + 1 || 1;
  res.send(`Visits: ${req.session.numberOfVisits}`);
});
