Cannot read properties of undefined (reading 'Model')

[FluffyDiscord]

Issue

I am unable to use this package as it seems to fail at Model declaration

Versions

• sequelize: 6.28.0
• sequelize-typescript: 2.1.5
• typescript: 4.9.5
• vite: 4.1.1

Issue type

• [x ] bug report
• [ ] feature request

Actual behavior

Trying to add/use model fails.

Expected behavior

Model loading should be working normally.

Steps to reproduce

1. create Mail.ts

import type {Optional} from "sequelize"
import {DataTypes} from "sequelize"
import {Column, Model, Table} from "sequelize-typescript"

interface MailAttributes
{
    id: number
    uid: number
    subject: string
    createdAt: Date
}

@Table
export default class Mail extends Model<MailAttributes, Optional<MailAttributes, "id">>
{
    @Column
    uid!: number

    @Column(DataTypes.TEXT)
    subject!: string

    @Column(DataTypes.DATE)
    createdAt!: Date
}

2. add it to sequelize

import {Sequelize} from "sequelize"

import Mail from "./model/Mail"

const sequelize = new Sequelize("postgres://dns", {
    logging: false,
    pool: {
        max: 10,
        min: 3,
        idle: 30000,
        acquire: 60000,
    },
})
sequelize.authenticate()


sequelize.modelManager.addModel(Mail)


export {sequelize, Mail}

3. try to use it

import {Mail, sequelize} from "../db/adapter.server"

const mail = Mail.build({
    uid: 0,
    createdAt: new Date(),
    subject: "test",
})
mail.save()

4. get error bellow

Internal server error: Cannot read properties of undefined (reading 'Model')

modelManager is never mentioned in the documentation.

import { Sequelize } from 'sequelize-typescript';
const sequelize = new Sequelize("postgres://dns", {
    logging: false, 
    pool: { 
        max: 10,
        min: 3,
        idle: 30000,
        acquire: 60000,
    },
    models:[Mail]
})

maybe better.
