     public void dismissAllModals(ViewController root, Options mergeOptions, CommandListener listener) {
         if (modals.isEmpty()) {
-            listener.onError("Nothing to dismiss");
             return;
         }

         String topModalId = peek().getId();
         String topModalName = peek().getCurrentComponentName();
         int modalsDismissed = size();
