jsPDF package is downloading as an empty PDF for html content in react (typescript)

Question

I am using jsPDF to download HTML content as pdf in react. I can download a pdf file, but it is showing an empty page only. If I use text for download like this

const doc = new jsPDF("p", "pt", "a4", true);
    doc.text("hello", 10, 20);
    doc.save();

it is downloading with the content "hello". But I use html to download,

const doc = new jsPDF("p", "pt", "a4", true);
var elem: any = document.getElementById("test");
doc.html(elem, {
      callback: (doc: any) => {
        doc.save(`Test.pdf`);
      }
    });

It is downloading as an empty page only. Since the tag changed to fromHTML to html, I need help on this. (previous discussions are a long time ago happened).
