How can i use @inject in constructor?

[paulocjota]

My controller code with IProductRepository interface:

export default class ProductsController {
  constructor(@inject('repositories.product') private productRepository: IProductRepository) {}
  ...
  }

Then i get error:

{
  "message": "Cannot inject \"[Function: Object]\" in \"[class ProductsController]\"",
  "help": "The value is not a valid class",
  "name": "RuntimeException",
  "status": 500,

      "isNative": false,
      "isApp": false
    },
    {
      "file": "app/interface_adapters/controllers/products_controller.ts",
      "filePath": "/data/workspace/sample/app/interface_adapters/controllers/products_controller.ts",
      "line": 10,
      "callee": "<anonymous>",
      "calleeShort": "<anonymous>",
      "column": 1,
      "context": {
        "start": 5,
        "pre": "  constructor(@inject('repositories.product') private productRepository: IProductRepository) {}\n\n  async index() {\n    return this.productRepository.findAll()\n  }",
        "line": "}",
        "post": ""
      },
      "isModule": false,
      "isNative": false,
      "isApp": true
    },

If i change controller code removing IProductRepository interface and adding the ProductRepositoryLucid (real implementation) class everything works fine:

`export default class ProductsController {
  constructor(@inject('repositories.product') private productRepository: ProductRepositoryLucid) {}
  ...
  }

but then i lose the benefits of @Inject.

If i create an abstract class and use it also works, but i hope there are better method:

import ProductEntity from '#domain/entities/product.entity'

export default interface IProductRepository {
  findAll(): Promise<ProductEntity[]>
  findById(id: number): Promise<ProductEntity | null>
  create(data: Partial<ProductEntity>): Promise<ProductEntity>
  update(id: number, data: Partial<ProductEntity>): Promise<ProductEntity>
  delete(id: number): Promise<void>
}

export abstract class ProductRepositoryContract implements IProductRepository {
  abstract findAll(): Promise<ProductEntity[]>
  abstract findById(id: number): Promise<ProductEntity | null>
  abstract create(data: Partial<ProductEntity>): Promise<ProductEntity>
  abstract update(id: number, data: Partial<ProductEntity>): Promise<ProductEntity>
  abstract delete(id: number): Promise<void>
}

// products_controller.ts
@inject()
export default class ProductsController {
  constructor(
    @inject('repositories.product') private productRepository: ProductRepositoryContract
  ) {}

In Laravel binding interface works out of the box:

Am i doing something wrong, or is this a typescript issue?
