How to fix " Path is required ,ValidationError " ,Mongoose ,node

Question

I have searched everywhere for this problem. but I cant find the correct way to fix it. help me to what is the problem.

    const router = require("express").Router();
    let Reg = require("../models/Register");

    http://localhost:8070/Register/add

  router.route("/add").post((req,res)=>{

const name = req.body.Name;
const email = req.body.Email;
const number = Number(req.body.Number);
const password = req.body.Password;


const NewAdd = new Reg({
    name,
    email,
    number,
    password

})

NewAdd.save().then(()=>{
    res.json("Registration Added")
}).catch((err)=>{
    console.log(err);
    res.json(err)
    console.log("reg err");
})



 })

and this is a module folder js

 const mongoose = require('mongoose');

 const Schema = mongoose.Schema;

 const RegSchema = new Schema({

Name: {
    type: String,
    required: true

},
Email: {
    type: String,
    required: true

},
Password: {
    type: String,
    required: true

},
Number: {
    type: Number,
    required: true

}

    });

     const Register = mongoose.model("Register",RegSchema);

      module.exports = Register;

This is server .js

    const express = require("express");
const mongoose = require("mongoose");
const bodyParser =require("body-parser");
const cors = require("cors");
 require("dotenv").config();
const app = express();

const PORT = process.env.PORT || 8070;

app.use(cors());
app.use(bodyParser.json());


const URL = process.env.MONGODB_URL;

mongoose.connect(URL,{
    useCreateIndex: true,
    useNewUrlParser: true,
    useUnifiedTopologyL: true,
    useFindAndModify: false
});

const connection = mongoose.connection;
connection.once("open", () =>{
    console.log("Mongodb connection success!");
})


const AddRouter = require("./routes/Registers.js");


app.use("/Register",AddRouter);



app.listen(PORT, () =>{
    console.log(`The port is : ${PORT}`);
})

error showing

Name: ValidatorError: Path Name is required. at validate (C:\Users\Sliit\Desktop\Reg-Backend\Travel-management-system\node_modules\mongoose\lib\schematype.js:1270:13) at C:\Users\Sliit\Desktop\Reg-Backend\Travel-management-system\node_modules\mongoose\lib\schematype.js:1253:7 at Array.forEach () at SchemaString.SchemaType.doValidate (C:\Users\Sliit\Desktop\Reg-Backend\Travel-management-system\node_modules\mongoose\lib\schematype.js:1198:14) at C:\Users\Sliit\Desktop\Reg-Backend\Travel-management-system\node_modules\mongoose\lib\document.js:2545:18 at processTicksAndRejections (node:internal/process/task_queues:78:11) { properties: [Object], kind: 'required', path: 'Name', value: undefined, reason: undefined, [Symbol(mongoose:validatorError)]: true } }, _message: 'Register validation failed' }

I testing API from the postman and get this error

Use the same case in "NewAdd" and in "RegSchema".

const NewAdd = new Reg({
  name,
  email,
  number,
  password
})

and

const RegSchema = new Schema({
  name: {
    type: String,
    required: true
  },
  email: {
    type: String,
    required: true
  },
  password: {
    type: String,
    required: true
  },
  number: {
    type: Number,
    required: true
  }
})
