HTTP 500 is not an HTTP error, it's a valid HTTP response code, only signals that the responding server can't deliver requested response due to an internal error. there is nothing wrong happend on HTTP side. that's why error event isn't emitted. You have to clearly distinguish between HTTP and the things that happens in Server/Client. It's not that surprising...
