 * When I click the button to generate the PDF, I get the console error
 *     ```
       Uncaught (in promise) Error: Unknown source type.
           at Promise.<anonymous> (html2pdf.min.js?ver=1.0.0:6)
       ```
   
 * Do I need to add something to my theme or template?

 * Solved my issue. The theme I was using was missing body_class() on the HTML body
   tag, so the plugin wasn’t finding the page when calling:
 * `var element = document.getElementsByClassName('wpexperts-page')[0];`
