javascript - 为什么 HtmlUnit 最新版本在无头模式下呈现 d3 版本 6 时会引发 JS 错误？

Question

我正在尝试在无头模式下使用 HtmlUnit 呈现包含 d3(d3.v6.3.1.min.js) 的 HTML。我正在使用最新版本的 HtmlUnit 。遇到一些问题。请找到以下详细信息。

我该如何解决？

这是我的代码：

WebClient webClient = new WebClient(BrowserVersion.BEST_SUPPORTED);
//webClient.getOptions().setThrowExceptionOnScriptError(false);
webClient.getOptions().setJavaScriptEnabled(true);
File file = new File("Path of the html");
HtmlPage page = webClient.getPage(file.toURI().toURL().toString());
String js = "var data = "+jsonSeries+";\n";
js += "drawChart(data);";
webClient.waitForBackgroundJavaScript(10000);
page.executeJavaScript(js);
svgImage = page.asXml().substring(page.asXml().indexOf("<svg"),page.asXml().indexOf("</svg>")+6);

这是错误日志：
