How do i fix this issue? (node, mysql & async/await)

Question

I'm new to this area and i'm testing some things with node.js (with express), mysql and async/await but i cannot find a way to fix this error:

const user = await con.query(sql, [EP.email, EP.password]);
                   ^^^ SyntaxError: Unexpected identifier at createScript (vm.js:74:10)

My Database Model:

var database = {};

database.con = async function() {

  const  mysql = require('mysql2/promise');

  const connection = await mysql.createConnection({
    host: "localhost",
    user: "root",
    database: "test",
    multipleStatements: true   });   }

module.exports = database;

My Accounts Model:

const database = require('../utils/database')

const con = database.con;

const Accounts = {};

      Accounts.getByEP = function (EP, callback) {

          var sql = "SELECT * FROM accounts WHERE email = ? and password = ?;";

          const user = await con.query(sql, [EP.email, EP.password]);

          callback(user);

      };

module.exports = Accounts;

Is there anything that i could do?

(PS: Sorry for my bad grammar i'm still learning english)

Answer 1

await is only supported syntax in functions that are tagged async . Accounts.getByEP is not an async function, so trying to await something in it will throw a syntax error. Writing async function (EP, callback) should fix it. Since the async function would already return a Promise, maybe the callback is not necessary :)

The error message is a bit unclear unfortunately.
