我的错误是：

const express = require('express');
    const app = express();
    const mysql = require('mysql');
    const router = express.Router();
    const path = require('path');
    const ifl = path.join(__dirname, '/views/assets/')
    
    app.set('view engine', 'ejs');
    app.use('/assets',express.static(ifl));
    
    //CONNECTION CONFIGURATION
    var con = mysql.createConnection({

       });
    
    app.get("/contact", (req, res)=>{
        res.render("contact");
    });
    
    app.get('/askquestion', (req, res) =>{
        con.query(`INSERT INTO contactq (name, email, subject, massage) VALUES ('${req.query.name}', '${req.query.email}', '${req.query.subject}', '${req.query.message}')`, function (err, result, fields) {

        });
    });
    
    app.listen(3000);
