Node.JS won't connect to MariaDB

I can't seem to get the example program to work from MariaDB's documentation.

Here's the code I am using which is a minimally modified version from the example in the docs.

const mariadb = require('mariadb');

const pool = mariadb.createPool({
    host: 'localhost',
    user: 'admin',
    password: 'adminpassword',
    database: 'userdb',
    port: 3306,
    connectionLimit: 5
});

async function f() {

    console.log(pool);

    let connection;
    
    try {
        console.log('Connection start');

        connection = await pool.getConnection();
        console.log('Connected');

        const rows = await connection.query('select * from users');
        console.log(rows);

        const res = await connection.query('insert into users value (?, ?)', [1, 'testuser']);
        console.log(res);

        await connection.release();
    }
    catch(exception) {
        console.log(exception);
    }

    if(connection) {
        return connection.end();
    }
}

f();

This is the output that I obtain if I run this code.

Node.js v19.3.0

My questions are any one of the following:

• Why does this happen?
• Where can I find the logs to obtain more information?
• Do I have to enable the logs, if so, how?
• How can I debug this issue?

I can connect perfectly fine using the CLI and Beekeeper Studio.
