ES6 async Router is not capturing the catch properly

[natarajanmca11]

I am using the following code. Global error handler not getting call If any error happens in service.

class UserRoute {
    public static async AddNewUser(req: Request, res: Response, next: NextFunction): Promise<void> {
        const service = ServiceFactory.CreateService(UserService, req);
        let v = await service.AddUser(req.body)
        res.send(v);
    }
}

let router: Router = express.Router();
router.post('/' + UserRoute.AddNewUser.name, UserRoute.AddNewUser);
export default router;

@natarajanmca11 You should wrap it. Express does not support async/promise function.
See use promise in http://expressjs.com/en/advanced/best-practice-performance.html#promises
And there is also an article mentioned in this page, https://strongloop.com/strongblog/async-error-handling-expressjs-es7-promises-generators/

To work around this for now, you can use something like https://github.com/blakeembrey/async-middleware. For native support, you might want to follow #2259.
