Route.post() requires a callback function but got a [object Undefined]? Why am I getting this error?

I'm working on the backend of my react project and I seem to be having some trouble with the backend for the info. When I do npm start I get an error saying Route.post() requires a callback function but got a [object Undefined] and I'm confused as to why.
Here is my server.js file
const express = require("express");
const cors = require("cors");
const dbConfig = require("./app/config/db.config");
const app = express();
var corsOptions = {
origin: "http://localhost:8081"
};
app.use(cors(corsOptions));
// parse requests of content-type - application/json
app.use(express.json());
// parse requests of content-type - application/x-www-form-urlencoded
app.use(express.urlencoded({ extended: true }));
const db = require("./app/models");
const Role = db.role;
db.mongoose
.connect(`mongodb+srv://tami00:MEUxClWqUNbLz359#cluster0.gmvao.mongodb.net/test?retryWrites=true&w=majority`, {
useNewUrlParser: true,
useUnifiedTopology: true
})
.then(() => {
console.log("Successfully connect to MongoDB.");
initial();
})
.catch(err => {
console.error("Connection error", err);
process.exit();
});
// simple route
app.use('/favourite', require('.app/routes/favourite.routes'));
// routes
// require(".app/routes/favourite.routes")(app);
require("./app/routes/auth.routes")(app);
require("./app/routes/user.routes")(app);
// set port, listen for requests
const PORT = process.env.PORT || 8080;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}.`);
});
function initial() {
Role.estimatedDocumentCount((err, count) => {
if (!err && count === 0) {
new Role({
name: "user"
}).save(err => {
if (err) {
console.log("error", err);
}
console.log("added 'user' to roles collection");
});
new Role({
name: "creator"
}).save(err => {
if (err) {
console.log("error", err);
}
console.log("added 'creator' to roles collection");
});
new Role({
name: "watcher"
}).save(err => {
if (err) {
console.log("error", err);
}
console.log("added 'watcher' to roles collection");
});
}
});
}
and here is my favourite.routes.js file. I have no issue with the other 2 routes.
const express = require('express');
const router = express.Router();
const{Favourite} = require("../models/favourite.model");
const {auth} = require("../middlewares/authJwt");
router.post("/favouriteNumber", auth, (req, res) => {
Favourite.find({"movieId": req.body.movieId})
.exec((err, favourite) => {
if(err) return res.status(400).send(err)
res.status(200).json({success: true, favouriteNumber: favourite.length})
})
})
router.post("/favourited", auth, (req, res) => {
Favourite.find({"movieId": req.body.movieId, "userFrom": req.body.userFrom})
.exec((err, favourite) => {
if(err) return res.status(400).send(err)
let result = false;
if(favourite.length !== 0) {
result = true
}
res.status(200).json({success: true, favourited: result});
})
})
router.post("/addToFavourite", auth, (req, res) => {
const favourite = new Favourite(req.body)
favourite.save((err, doc) => {
if(err) return res.json({success: false, err})
return res.status(200).json({success: true, doc})
})
})
router.post("/removeFavorite", auth, (req, res) => {
Favourite.findOneAndDelete({movieId: req.body.movieId, userFrom: req.body.userFrom})
.exec((err, doc) => {
if(err) return res.json({success: false, err})
return res.status(200).json({success: true, doc})
})
})
module.exports = router;
This is the favourite models where I'm creating the mongoose schema
const mongoose = require('mongoose');

},

Heres the middlewares auth file
const jwt = require("jsonwebtoken");
const config = require("../config/auth.config.js");
const db = require("../models");
const User = db.user;
const Role = db.role;
verifyToken = (req, res, next) => {
let token = req.headers["x-access-token"];
if (!token) {
return res.status(403).send({ message: "No token provided!" });
}
jwt.verify(token, config.secret, (err, decoded) => {
if (err) {
return res.status(401).send({ message: "Unauthorized!" });
}
req.userId = decoded.id;
next();
});
};
isAdmin = (req, res, next) => {
User.findById(req.userId).exec((err, user) => {
if (err) {
res.status(500).send({ message: err });
return;
}
Role.find(
{
_id: { $in: user.roles }
},
(err, roles) => {
if (err) {
res.status(500).send({ message: err });
return;
}
for (let i = 0; i < roles.length; i++) {
if (roles[i].name === "admin") {
next();
return;
}
}
res.status(403).send({ message: "Require Admin Role!" });
return;
}
);
});
};
isModerator = (req, res, next) => {
User.findById(req.userId).exec((err, user) => {
if (err) {
res.status(500).send({ message: err });
return;
}
Role.find(
{
_id: { $in: user.roles }
},
(err, roles) => {
if (err) {
res.status(500).send({ message: err });
return;
}
for (let i = 0; i < roles.length; i++) {
if (roles[i].name === "moderator") {
next();
return;
}
}
res.status(403).send({ message: "Require Moderator Role!" });
return;
}
);
});
};
const authJwt = {
verifyToken,
isAdmin,
isModerator
};
module.exports = authJwt;

const {auth} = require("../middlewares/authJwt"); uses destructuring, but your exports from ../middlewares/authJwt don't have a field auth.
auth therefore is undefined.

node.js passport deserializeUser not being called

In localhost, deserializeUser is being called, and there was no problem.
But after we deploy our app to ec2 using nginx(react), deserializeUser is never called.

login and register have no problem, but I couldn't use any functions needed login session or cookies. How I solve this problem?

Since the release of Google Chrome 80 on February 4, 2020, the default value of Cookie's SameSite property has been changed from None to Lax.
In other words, if you send an intersection request, not the same domain address, the cookie will not work.
The solution was to change the cookie settings to sameSite none in backend app.js.
But if you change it, you have to put the attribute secure true, and it was only possible in https.
Even if it is not https, if front and backend are using the same domain, there is no problem.
I believe that applying the domain will not result in an error, because eventually you have to have a domain to apply for https

sockiet.ion passport.js, express.js and authentication headers

My chrome extension was working perfectly until recently.
I originally received a error message of
required same site none and secure in the header
I then added to my express.session config,
samesite:none, secure:true
Now instead of that error, I am unable to gain access to my website by login in with my chrome extension, which I believe is due to socket.io not maintaining the authentication cookie.
My express server is as below,
const config = require('../../config');
const express = require('express');
const app = express();
const server = require('http').createServer(app);
const io = require('socket.io')(server, { wsEngine: 'ws' });
const mysql = require('mysql');
const expressSession = require('express-session');
const ExpressMysqlSessionStore = require('express-mysql-session')(expressSession);
const sharedsession = require('express-socket.io-session');
const path = require('path');
const utils = require('./utils');
// remove from header "X-Powered-By: Express"
app.disable('x-powered-by');
server.listen(config.serverParams.port, config.serverParams.address, () => {
console.log(`Server running at http://${server.address().address}:${server.address().port}`);
});
/* DATABASE */
global.db = mysql.createConnection(config.db);
db.connect();
/* DATABASE */
/* SESSION */
const sessionStore = new ExpressMysqlSessionStore(config.sessionStore, db);
const session = expressSession({
...config.session,
store: sessionStore,
});
app.use(session);
/* SESSION */
app.use(express.static(config.frontendDir));
app.get([
'/signup',
'/stats',
'/pay',
], (req, res) => res.sendFile(path.join(`${config.frontendDir}${req.path}.html`)));
io.use(sharedsession(session, {
autoSave: true
}));
io.on('connection', socket => {
socket.use((packet, next) => {
if (packet[0]) {
console.log('METHOD:', packet[0]);
const sessionData = socket.handshake.session.user;
const noSessionNeed = [ 'login', 'signup', 'checkAuth' ].includes(packet[0]);
let error;
if ( ! sessionData && ! noSessionNeed) error = { code: -1, message: 'You need to login in extension!' };
if (error) return next(new Error(JSON.stringify(error)));
else next();
}
});
const auth = require('./auth')(socket);
socket.on('checkAuth', auth.checkAuth);
socket.on('login', auth.login);
socket.on('signup', auth.signup);
socket.on('logout', auth.logout);
const users = require('./users')(socket);
socket.on('users.get', users.get);
const sentiment = require('./sentiment')(socket);
socket.on('sentiment.get', sentiment.get);
socket.on('sentiment.set', sentiment.set);
socket.on('disconnect', () => {
});
});
And the config file is somewhat like this,
config.session = {
// globals.config.express.sessionSecret
resave: true,
saveUninitialized: true,
cookie: {
maxAge: 86400000,
/* FOR WORK ON LOCALHOST
secure: true,
sameSite: 'lax', */
sameSite:"None",
secure:true,
domain: '.xx.xx',
},
Here is how the authentication is done with the socket.io
const passport = require('passport');
/* PASSPORT */
require('./passport')(passport); // pass passport for configuration
/* app.use(passport.initialize());
app.use(passport.session()); */
/* PASSPORT */
const utils = require('./utils');
const bcrypt = require('bcrypt');
const saltRounds = 10;
module.exports = socket => {
this.checkAuth = fn => {
if (fn) fn();
};
this.login = (params, fn) => {
passport.authenticate('local-login', (err, user) => {
const response = {};
if (user) {
socket.handshake.session.user = user;
socket.handshake.session.save();
response.message = 'Your successful login!';
response.data = {
id: user.id,
username: user.username,
};
}
else if (err) {
response.error = {
code: err,
message: ''
};
if (err == -1) response.error.message = 'Incorrect username or password!';
}
if (fn) fn(response);
})({ body: params });
},
// socket.on('signup', (params, fn) => {
this.signup = (params, fn) => {
passport.authenticate('local-signup', (err, user) => {
const response = {};
if (user) {
console.log('signup', user);
response.message = 'Your successful signup!';
}
else if (err) {
response.error = {
code: err,
message: ''
};
if (err == -1) response.error.message = 'User alreay exist!';
}
if (fn) fn(response);
})({ body: params });
};
// socket.on('logout', fn => {
this.logout = fn => {
delete socket.handshake.session.user;
};
return this;
};
utils
module.exports = socket => {
// socket.on('users.get', fn => {
this.get = fn => {
if (fn) {
const response = {};
response.data = {
id: socket.handshake.session.user.id,
username: socket.handshake.session.user.username,
};
fn(response);
}
};
return this;
};
Would love to be able to solve this issue :P
Thanks!

This was solved by using a JWT token, separate from this, to solve the issue of the socket.io session.s

Maybe it has to do with the signup function? I think there's no sign up option for first-comers. Try making if (user) -> if (!user)

Then I have a javscript dedicated to testing
let assert = require('assert');
let chai = require('chai');
let chaiHttp = require('chai-http');
let serverAndSchema = require('../index');
let server = serverAndSchema.app
let Bill = serverAndSchema.schema
let should = chai.should();
chai.use(chaiHttp);
describe('Bills', function() {
describe('/GET bill', function() {
it('should get the specified bill', function(done) {
let expectedBill = new Bill({
type: "Test Type",
dueDate: "12/3/2018T06:00:00.000Z",
company: "Test Company",
amtDue: "100",
paidStatus: "Test Status"
});
expectedBill.save(function(err, savedBill) {
chai.request(server)
.get('/api/bills/'+savedBill.id)
.end((err, res) => {
res.should.have.status(200);
res.body.should.be.a('object');
res.body.should.have.property('type').eql(savedBill.type)
res.body.should.have.property('dueDate').eql(savedBill.dueDate)
res.body.should.have.property('company').eql(savedBill.company)
res.body.should.have.property('amtDue').eql(savedBill.amtDue)
res.body.should.have.property('paidStatus').eql(savedBill.paidStatus)
res.body.should.have.property('_id').eql(savedBill.id)
done();
})
});
});
});
});
The data is added to my database, but I get this error when I try to run the test:
Uncaught TypeError: Cannot read property 'id' of undefined
at
C:\Users\Martae\Documents\Github\BillTracker\test\bill.js:29:46
Any help with this is appreciated!

When I checked the Bill schema, I found that the issue is caused by your due date format. So, the mongo saved is failed and you got undefined for savedBill and when you try to access id, it throws the error that you got.
Here is the solution:
let expectedBill = new Bill({
type: "Test Type",
dueDate: "2018-03-13T06:00:00.000Z", // change date to standardized format
company: "Test Company",
amtDue: "100",
paidStatus: "Test Status"
});
expectedBill.save(function(err, savedBill) {
const id = savedBill._id; // store id, it is always returned as _id
chai.request(server)
.get('/api/bills/'+id)
.end((err, res) => {
// ...
done();
});
});

How to debug "Cannot POST /" error?

I am getting this error:
Cannot POST/.
Below is the code I'm trying to execute.
Server.js

});
I've been trying this but not getting through.Not sure whether the html file I have is correct. Want to create an html file to post from, but mine is refusing to respond.

You cannot POST to / because you haven't defined a route handler for POST requests to / (you only have one for GET to /).
