Node.js Awillix:TypeError:无法读取属性'；电影服务'；未定义的

我正在尝试使用Express.js和Awillix创建简单的应用程序以进行依赖项注入，但是我正在努力使用依赖项服务，因为它总是未定义的。 我得到的错误是：

TypeError: Cannot read property 'movieService' of undefined
    at MovieController.findById (/home/mat/Projects/movies-ts/src/movie-controller.ts:17:26)

MovieController是一个使用MovieService依赖项的类。MovieService什么也不做，它只是返回一些字符串来测试注入。看起来是这样的：

enum Routes {
    FindById = '/'
}

(async () => {
    const container: AwilixContainer = await createContainer();
    const app = express();

    const movieController = container.resolve('movieController') as MovieController;

    const router = express.Router();
    router.get(Routes.FindById, movieController.findById);
    app.use(router);

    app.listen(3000, () => {
        console.log(`Listening in port ${3000}`)
    })
    
})();

电影服务：

export default class MovieService {

    constructor() { }

    findById(id: number): string {
        return `Found user with id ${id}`;
    }
}

export default class MovieController {
    movieService: MovieService;

    constructor(movieService: MovieService) { 
        this.movieService = movieService;
    }

    findById(req: Request, res: Response) {
        const msg = this.movieService.findById(1234); <- This gives undefined
        return msg;
    }
}

MovieController（保留MovieService的依赖项）：

我错过了什么

enum Routes {
    FindById = '/'
}

(async () => {
    const container: AwilixContainer = await createContainer();
    const app = express();

    const movieController = container.resolve('movieController') as MovieController;

    const router = express.Router();
    router.get(Routes.FindById, movieController.findById);
    app.use(router);

    app.listen(3000, () => {
        console.log(`Listening in port ${3000}`)
    })
    
})();
