NodeJS invalid syntax in function

Question

SyntaxError: Invalid or unexpected token line 5

I cant seem to find what is missing or where the syntax is wrong

const getData = () => {
    return new Promise((resolve) => {
        const connection = createConnection();
        const sqlQuery = fs.readFileSync('./file.sql').toString();
      
        connection.connect((err) => {
            if (err) {
                console.log('Error connecting to Db:' + err);
                return;
            }
            console.log('Database connection established.');
            connection.query(sqlQuery, (err, results, fields) => {
                if (err) throw err;
                connection.end((err) => {
                    if (err) {
                        console.log(err);
                    }
                    console.log('Database connection closed.');
                    resolve(results);
                });
            });
        });
    });
};

You seem to have a hidden character the example. `` shows as a red dot in prettier. Try deleting the characters in between `toString();` and `connection`? — evolutionxbox, Mar 11 '21 at 14:40
The `Promise()` won't resolve or reject when `.connect()` fails. — Andreas, Mar 11 '21 at 14:41

Try deleting line 5 by backspacing it so that your new line 5 is now connection.connect((err) => { There is thing called an "invisible character" that can be created when copying and pasting code. Notice that when you hover over the syntax error in the dev tools on the browser it gives you \u200b. Here is another article discussion on stackoverflow that may be helpful:here
