nest: Route params decorators bug in ES

Route params decorators not working properly in ES

I’m trying to use @Body decorator, but I’m getting unwanted results:

  @Post('/signup')
  async signUp (
    @Request() req, 
    @Response() res,
    @Body('username') username,
    @Body('password') password ) {
      console.log(username) //[Function: next] 
      console.log(password) //undefined
    }

Then I tried to send the @Body decorator arguments first, but when printing them I got equivalents to the Request, Response and Next in their respective order.

  @Post('/signup')
  async signUp (
    @Body('username') username,
    @Body('password') password,
    @Request() req, 
    @Response() res
  ) {
      console.log(username) //IncomingMessage {.........  <- req equivalent
      console.log(password) //ServerResponse {...... <- res equivalent
      console.log(req) //[Function: next]  <- next equivalent
      console.log(res) //undefined
    }

I think the problem is with the order or obligation of the params
