Does not throw error when querying a non existent view/designdoc

Here is the code I used. This doesn't call onError.

ViewQuery queryTemplate = ViewQuery.from("test","dummy");
queryTemplate.stale(Stale.FALSE);
Observable<ViewRow> viewRowObservable = bucket.query(queryTemplate).flatMap(new Func1<ViewResult, Observable<ViewRow>>() {
public Observable<ViewRow> call(ViewResult res)

{ return res.rows(); }

});

viewRowObservable.subscribe(new Observer<ViewRow>() {
@Override
public void onCompleted()

{ System.out.println("Completed"); }

@Override
public void onError(Throwable throwable)

{ System.out.println(throwable.getMessage()); }

@Override
public void onNext(ViewRow viewRow) {
}
});
