});
app.put('/updatedata',function(req,res){
    
    connection.query('update hp set Name=?,Address=?,Country=?,Phone=? where Id=?',[req.body.Name,req.body.Address,req.body.Country,req.body.Phone,req.body.Id],function(error,results,fields){
        if(err) throw err;
        console.log("Record updated");
        res.redirect('/home');
    });

app.get('/home', function(request, response) {
    
    response.sendFile(__dirname + '/home.html');
});
app.listen(5000);
console.log('Server Started');**

Answer 1

The title indicates you do a POST on /updatedata, but you define the PUT method for /updatedata in your code. Try to replace app.put('/updatedata' with app.post('/updatedata'.
