What is causing the type error in my code?

I am trying to console.log the input in this sign up form but every time i fill the details and the submit the form then it shows the following error
TypeError: Cannot read properties of undefined (reading 'fName')
Kindly let me know the error in my code.
<form action="/" method="POST">
<img class="mb-4" src="images/mail.jpg" alt="" width="72" height="57">
<h1 class="h3 mb-3 fw-normal">Signup the Newsletter</h1>
<div class="form-floating">
<input type="text" name="fName" class="form-control top" placeholder="First Name">
</div>
<div class="form-floating">
<input type="text" name="lName" class="form-control middle" placeholder="Last Name">
</div>
<div class="form-floating">
<input type="email" name="email" class="form-control bottom" placeholder="name#example.com">
</div>
<button class="w-100 btn btn-lg btn-primary" type="submit">Sign in</button>
<p class="mt-5 mb-3 text-muted">Follow me</p>
</form>
// const https = require("https");
const bodyParser = require("body-parser");
const request = require("request");
const app = express();
app.use(express.static("public"));
app.use(bodyParser.urlencoded({extended:true}));
app.get("/", function(req, res) {
res.sendFile(__dirname + "/signup.html");
});
app.post("/", function(res, req){
var firstName = req.body.fName;
var middleName = req.body.lName;
var eMail = req.body.email;
console.log(firstName, middleName, eMail);
});
app.listen(3000, function() {
console.log("Server is running on Port 3000");
}); ```

I found these errors in your code, check them and it will work fine.
app.use("/public", express.static(path.join(__dirname, 'public'))); // use this for defining your public folder (and don't forget to import path module above).
app.post("/", function(req, res, next){
var firstName = req.body.fName;
var middleName = req.body.lName;
var eMail = req.body.email;
console.log(firstName, middleName, eMail);
});
Here as you can see in the callback function we get three parameters first will be the request object, second will be the response object and third is optional next object.
But in your case you are reading it from response object but it should be from request.
Thanks

Why can't I successfully to fetch url from form and thus attribute it to the source(src) of images?

I've having an issue I shouldn't be having with my Node/Express code(s). I can't for the life of me get the image source (src) attribute to work, hence the images added from a form aren't being displayed. It just displays as unknown. I have no idea where I'm going wrong, and have gone through the whole code(s) multiple times, but nothing seems out of place.
The JS code is as follows:
var express = require("express"),
app = express(),
bodyParser = require("body-parser"),
mongoose = require("mongoose");
mongoose.connect("mongodb://localhost/yelpcamp");
app.use(bodyParser.urlencoded({extended: true}));
app.set("view engine", "ejs");
//Camp Schema
var campgroundSchema = new mongoose.Schema({
name: String,
image: String
});
var Campground = mongoose.model("Campground", campgroundSchema);
app.get("/", function(req, res) {
res.render("landing");
});
app.get("/campgrounds", function(req, res){
Campground.find({}, function(err, sites) {
if(err) {
console.log(err);
}
else {
res.render("campgrounds", {
campgrounds:sites
});
}
});
});
app.post("/campgrounds", function(req, res){
//Fetching data from form
var name = req.body.campName;
var url = req.body.imageUrl;
var newCamp = {
name: name,
image: url
};
//New Campground and Save to DB
Campground.create(newCamp, function(err, campground) {
if(err) {
console.log(err);
}
else {
//Redirect to Camp Page
console.log(campground);
res.redirect("/campgrounds");
}
});
});
app.get("/campgrounds/new", function(req, res){
res.render("new");
});
app.listen(4500, function(){
console.log("Yelp Camp Server Started!!!");
});
The following are the relevant EJS codes:
Form EJS
<div class="container">
<form action="/campgrounds" method="POST">
<label for="campName">Name</label>
<input type="text" id="campName" name="campName" placeholder="Add Campground Name">
<label for="campImage">Image</label>
<input type="url" id="campImage" name="imageUrl" placeholder="Add Image Url">
<input type="submit" name="submit" value="Add Campground">
</form>
Go Back
</div>
Add Image EJS
<div class="container">
<h1 style="margin-top: 8%;">Campgrounds Presentation</h1>
<div class="row">
<% campgrounds.forEach(function(campground) { %>
<div class="col-md-4 col-sm-6 col-xs-12">
<div class="thumbnail">
<img src="<%= campground.image %>">
<h3 class=text-center><%= campground.name %></h3>
</div>
</div>
<% }); %>
</div>
</div>

Passport JS does not give error but, does not seem to work

I have a basic register and login app. After the user registers, and stores their information into my sequelize model, I redirect the page to the login page. When I try to login with the username and password I just made, it doesn't throw any errors, but the page goes into an endless loading phase where it eventually says The localhost page isnt working localhost didn't send any data'ERR_EMPTY_RESPONSE`

You only handle POST requests to /friend-book/login.
When you use res.redirect('/friend-book/login'), it'll redirect the user using GET method to that URL.
router.get('/friend-book/login', function (req, res) {
res.render('login');
});
