I am trying to render the HTML containing d3(d3.v6.3.1.min.js) using HtmlUnit in headless mode. I am using the latest version of HtmlUnit . Getting some issue. Please find the below details.

How can I fix it?

Here is my code :

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);

Here is the error log :
