The requested module './modules/data.js' does not provide an export named 'default'

Выдает ошибку, пытаюсь перейти на ECMAScript и делать импорт модулей через import, а не require, но что-то пошло не так и я не понимаю, что именно, помогите пожалуйста.

import mysql from "mysql2"
import mysqlPromise from "mysql2/promise"
import pg from 'pg'
var connection, connectionPromise
function setDataConnection(type, host, port, database, user, password) {
    if (type == "mysql") {
        connection = mysql.createPool({
            host: host || "127.0.0.1",
            port: port || 3306,
            database: database,
            user: user || "root",
            password: password || ""
        })
        connectionPromise = mysqlPromise.createPool({
            connectionLimit:  15,
            host: host || "127.0.0.1",
            port: port || 3306,
            database: database,
            user: user || "root",
            password: password || ""
        })
        console.log("[MySQL] База данных подключена!")
    }
    else {
        connection = new pg({
            host: host || 'localhost',
            port: port || 5432,
            user: user || 'postgres',
            password: password || 'postgres',
        });
        console.log("[PostgreSQL] База данных подключена!")
    }
}

exports.setDataConnection = setDataConnection;
async function tableExists(pool, tableName) {
    try {
        const query = `SELECT 1 FROM ${tableName} LIMIT 1;`;
        await pool.execute(query);
        return true;
    } catch (err) {
        return false;
    }
}
var query = async function (sql) {

        let rows = await connectionPromise.execute(
            sql,
        );
        return rows[0]
    } catch (error) {

    }

        );
        return console.log("Data added succesfully!")
    } catch (error) {
        console.log(error);
    }
}
exports.querySet = querySet
