Errors when defining @ForeignKey and @BelongsTo decorator

[Johnathon332]

Versions

• sequelize: 5.21.5
• sequelize-typescript: 1.1.0
• typescript: 3.8.3

I'm submitting a ...

[x ] bug report
[ ] feature request

Actual behavior:

There are actually two errors that I am facing one of which is with the @foreignkey decorator and the other being the @BelongsTo decorator.

• Foreign key error being

Property 'isInitialized' is missing in type 'typeof Product' but required in type 'typeof Model'.

• BelongsTo error being

No overload matches this call.
Overload 1 of 2, '(associatedClassGetter: ModelClassGetter, foreignKey?: string | undefined): Function', gave the following error.
Type 'typeof Product' is not assignable to type 'typeof Model'.
Overload 2 of 2, '(associatedClassGetter: ModelClassGetter, options?: BelongsToOptions | undefined): Function', gave the following error.
Type 'typeof Product' is not assignable to type 'typeof Model'

Expected behavior:
I followed the documentation of how to define these decorators, this should work

Steps to reproduce:

Here is the application I am working on https://github.com/Johnathon332/FirstNodeApp

Related code:

import { Model } from 'sequelize/types';
import {
  Table,
  Column,
  CreatedAt,
  UpdatedAt,
  DataType,
  IsDate,
  NotEmpty,
  PrimaryKey,
  AutoIncrement,
  AllowNull,
} from 'sequelize-typescript';

@Table
export class Product extends Model<Product> {
  @PrimaryKey
  @AutoIncrement
  public id!: number;

  @Column(DataType.STRING)
  @AllowNull(false)
  @NotEmpty
  public name!: string;

  @Column(DataType.DECIMAL)
  @AllowNull(false)
  @NotEmpty
  public price!: number;

  @CreatedAt
  public readonly createdAt!: Date;

  @UpdatedAt
  public readonly updatedAt!: Date;
}

import { Model } from 'sequelize/types';
import {
  Table,
  Column,
  NotNull,
  DataType,
  PrimaryKey,
  AutoIncrement,
  ForeignKey,
  CreatedAt,
  UpdatedAt,
  BelongsTo,
} from 'sequelize-typescript';
import { Product } from './Product';

@Table
export class Order extends Model<Order> {
  @PrimaryKey
  @AutoIncrement
  @Column
  public id!: number;

  @ForeignKey(() => Product)
  @Column
  public productId!: number;

  @BelongsTo(() => Product)
  public product!: Product;

  @Column(DataType.NUMBER)
  public quantity!: number;

  @CreatedAt
  public createdAt!: Date;

  @UpdatedAt
  public updatedAt!: Date;
}

Hey @Johnathon332, you've imported the wrong Model reference:

- import { Model } from 'sequelize/types';
import {
+ Model,
  Table,
  Column,
  NotNull,
  DataType,
  PrimaryKey,
  AutoIncrement,
  ForeignKey,
  CreatedAt,
  UpdatedAt,
  BelongsTo,
} from 'sequelize-typescript';
import { Product } from './Product';

@Table
export class Order extends Model<Order> {
