Javascript – How do I submit a form in Node.js?

I’m having an issue with the submission of the information from this form I created with Node.js. Can someone please help me? I’m receiving the following error:

TypeError: Cannot read properties of undefined (reading 'conteudo')

my code

const express=require("express");
const app=express();
const handlebars=require("express-handlebars");
const Sequelize=require("sequelize");


const sequelize=new Sequelize("test","root","88182231",{
    host:"localhost",
    dialect:"mysql"
})

app.get("/card",function(req,res){
    res.render("form")
})

app.post("/add",function(req,res){
     res.send("conteudo:"+req.body.conteudo+" titulo:"+req.body.titulo)
})

app.engine("handlebars", handlebars.engine({ defaultLayout: "main" }));
app.set("view engine","handlebars");
app.use(express.urlencoded({extended:false}))
app.use(express.json())

I have already tried changing my database, even the data type from TEXT to STRING, and nothing.

    You have to use express.json() middleware. It parses incoming requests with JSON payloads and you can access the passed data using req.body.

    so add app.use(express.json()) somewhere after const app=express();;

    it needs reorder codes

    const express=require("express");
const app=express();
const handlebars=require("express- 
handlebars");
const Sequelize=require("sequelize");

 app.engine("handlebars", handlebars.engine({ 
 defaultLayout: "main" }));
app.set("view engine","handlebars");
app.use(express.urlencoded({extended:false}))
app.use(express.json())

const sequelize=new 
Sequelize("test","root","88182231",{
host:"localhost",
dialect:"MySQL"
 })

 app.get("/card",function(req,res){
 res.render("form")
   })

app.post("/add",function(req,res){
  res.send("conteudo:"+req.body.conteudo+" 
titulo:"+req.body.titulo)
})
