and the running code is here:

    ManagerApi.getIns().updateChannelInfoForMobileUser(AppHelper.getIUser().getMobileUserId(), ((XhEvent.BindEvent) event).getmChannelId(), ((XhEvent.BindEvent) event).getmUserId())
                                .subscribeOn(Schedulers.io()).observeOn(Schedulers.io()).subscribe(new Action1<EduCommResponse>() {
                            @Override
                            public void call(EduCommResponse eduCommResponse) {
                                if (eduCommResponse.isSuccess()) {
                                    RememberMe.get().devBindedUser();
                                }
                            }
                        });

when the http response code is 500 ,will throw this error

The key message is:

Add onError handling.

i.e., use subscribe(Action1<T>, Action1<Throwable>) at least.
