Я использовал модуль 'node-adodb' nodejs с базой данных .mdb. Вот мой код.
const ADODB = require('node-adodb');
const connection = ADODB.open(`Provider=Microsoft.Jet.OLEDB.4.0;Data Source=${__dirname}/data/Database.mdb;`);
module.exports = { connection : connection };
Это работает на локальном и выдает следующую ошибку после размещения на Heroku.
throw new ERR_INVALID_ARG_TYPE(name, 'string', value);
