ScriptException (missing formal parameter) when trying to access a simple page

[LucasLaacerda]

I need to load a page but it is returning failures

Code: `import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.junit.Test;

import com.gargoylesoftware.htmlunit.WebClient; import com.gargoylesoftware.htmlunit.html.HtmlDivision; import com.gargoylesoftware.htmlunit.html.HtmlPage; import com.gargoylesoftware.htmlunit.javascript.host.dom.NodeList;

public class WebCaptura {

 public static void main(String[] args){

     //String url = "https://g1.globo.com/";

    try(final WebClient webClient = new WebClient()) {
         final HtmlPage page = webClient.getPage("https://g1.globo.com/");

    }catch (Exception e) {
        e.printStackTrace();
    }

}

} `

log:

Hi Lucas,

looks like a problem with the js in the page. There is code like b=new Map([...o(e.ex),...o(e.im)]) in fact this uses the javascript rest operator and this is unfortunately not supported by rhino so far.

And btw: The page is not simple, is like any other news page a horrible monster filled with tons of js to confuse and track the user....
