Can't run login with two factor authentication - blog

I am following the blog by Nevo for creating a registration and login with two factor authentication on react. Link: https://novu.co/blog/creating-a-registration-and-a-login-with-two-factor-authentication-on-react/. I'm relatively new to react and the web dev side of programming. Though the blog started quite well with the react code for the login and the signup page. But once it started creating the authentication work flow, I lost it how the codes were supposed to be edited. Also the github to this blog isn't update with this code. I've a few questions/errors: 1. Is the API calls on port 4000 and not 3000? As seen in code in Login.js

`fetch("http://localhost:4000/api/login",

`fetch("http://localhost:4000/api/login",

? 2. After SignUp, I'm not able to login with my credentials. Is there something wrong with my code? 3. I'm editing the code in Login.js with

pp.post("/api/login", (req, res) => {

    //:point_down_tone1: Accepts the user's credentials

    const { email, password } = req.body;

    //:point_down_tone1: Checks for user(s) with the same email and password

    let result = users.filter(

        (user) => user.email === email && user.password === password

    );


    //:point_down_tone1: If no user exists, it returns an error message

    if (result.length !== 1) {

        return res.json({

            error_message: "Incorrect credentials",

        });

    }

    //:point_down_tone1: Returns the username of the user after a successful login

    res.json({

        message: "Login successfully",

        data: {

            username: result[0].username,

        },

    });

});

pp.post("/api/login", (req, res) => {

    //:point_down_tone1: Accepts the user's credentials

    const { email, password } = req.body;

    //:point_down_tone1: Checks for user(s) with the same email and password

    let result = users.filter(

        (user) => user.email === email && user.password === password

    );


    //:point_down_tone1: If no user exists, it returns an error message

    if (result.length !== 1) {

        return res.json({

            error_message: "Incorrect credentials",

        });

    }

    //:point_down_tone1: Returns the username of the user after a successful login

    res.json({

        message: "Login successfully",

        data: {

            username: result[0].username,

        },

    });

});

I'm getting an error

ERROR

src\components\Login.js
  Line 38:2:   'pp' is not defined     no-undef
  Line 46:16:  'users' is not defined  no-undef

Best would be to look into my repository: https://github.com/syedjawadakhtar/auth-system This is the start of a small project I'm doing and it will of great help.
