Ошибка «ConnectionError [SequelizeConnectionError]: не удалось подключиться к локальному узлу: 1443 - Не удалось подключиться (последовательность)» с помощью sequelize-automate

Question

Я получаю сообщение об ошибке подключения при попытке автоматического создания моделей таблиц БД с помощью sequelize-automate.

Однако подключение, которое я использую для sequelize, работает, но оно в другом формате, и я Я не уверен, позволяет ли sequelize-automate использовать тот же формат.

const Sequelize = require('sequelize');
const util = require('util');
const dbSequelize = require('../public/dbconfigSequelize.json');

let databaseUrl = util.format(
  dbSequelize.server,
  dbSequelize.username,
  dbSequelize.password,
  dbSequelize.host,
  dbSequelize.database
)

function getConnection() {
  console.log('creating a new connection');
  return new Sequelize(databaseUrl, {
    pool: {
      max: 1
    },
    logging: console.log
  });
}

function checkAuthenticate() {
  sequelize
    .authenticate()
    .then(() => {
      console.log('Connection has been established successfully.');
    })
    .catch(err => {
      console.error('Unable to connect to the database:', err);
    });
}

const sequelize = getConnection();
checkAuthenticate();

module.exports = sequelize;

Проверьте это, это не от sequelize-автоматизировать, но вполне вероятно, что ваша проблема не относится к этому в любом случае, в противном случае это было бы хорошо задокументировано другими

не могу не заметить, что ошибка в названии не совпадает с ошибкой в ​​приведенной выше трассировке ... почему он использует порт по умолчанию для mySQL вместо ms sql
