Adding mongoose schema model to express results in error 500 - express

Question

I have react app that stores data via axios to a mongoose server. It worked perfect until I wanted to add an extra schema for different data. My schema models are separated so I thought to just add another one called PartyList.js.
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
// Define collection and schema for Items
var PartyList = new Schema({
name: {
type: String
},
song_id: {
type: String
},
port: {
type: Number
}
},{
collection: 'party'
});
module.exports = mongoose.model('PartyList', PartyList);
This is the code in my app.js.
const config = require('./database/DB');
const ServerPortRouter = require('./routes/ServerPortRoutes');
mongoose.connect(config.DB).then(
() => {console.log('Database is connected') },
err => { console.log('Can not connect to the database' +err)
});
app.use('/serverport', ServerPortRouter);
This is how I import it and try to run it (called ServerPortRoutes.js). After running a part of my application that uses this route I get a 500 (Internal Server Error). My server tells me ReferenceError: PartyList is not defined which is defined 3 lines above.
const ServerPort = require('../models/ServerPort');
const PartyList = require('../models/PartyList');
ServerPortRouter.route('/add-party').post(function (req, res) {
const PartyList = new PartyList(req.body);
PartyList.save()
.then(PartyList => {
res.json('Server added successfully');
})
.catch(err => {
res.status(500).send("unable to save to database");
});
});

The problem looks to be you are redefining a const . In your route change to const partyList = new PartyList(req.body); Then use partyList as your variable
