htmlunit 播放列表下载抛出错误

问题描述

我正在尝试使用 Htmlunit2.50.0 下载 Youtube Playlist 个视频，以下是我的代码：

 WebClient webClient = new WebClient(BrowserVersion.BEST_SUPPORTED);
            webClient.getOptions().setThrowExceptionOnScriptError(false);
            webClient.setCssErrorHandler(new SilentCssErrorHandler());
            webClient.setAjaxController(new NicelyResynchronizingAjaxController());
            webClient.getOptions().setCssEnabled(true);
            webClient.getOptions().setRedirectEnabled(false);
            webClient.getOptions().setAppletEnabled(false);
            webClient.getOptions().setJavaScriptEnabled(true);
            webClient.getOptions().setPopupBlockerEnabled(true);
            webClient.getOptions().setTimeout(10000);

       HtmlPage currentPage = webClient.getPage("https://www.youtube.com/watch?v=dD2EISBDjWM&list=PLr6-GrHUlVf_ZNmuQSXdS197Oyr1L9sPB");
  
         System.out.println(currentPage.asNormalizedText());
         webClient.close();

但我收到以下错误：

如果我从那里获取当前页面，我可以迭代列表并单击每个项目进行下载，但它在当前页面本身抛出错误。
