Hyperlinks missing generated pdf

Hi. I'm generating a PDF document from a Word docx template with the PDF Services Node.js SDK. I'm pretty much following the quick start here: https://udp.adobe.io/document-services/docs/overview/document-generation-api/quickstarts/nodejs/.

The docx template contains a hyperlink button. I'm noticing this button is no longer a link in the generated pdf file. Does this indicate an issue on the Microsoft Word side or am I missing some kind of parameter when generating the PDF in the js code? Thanks!
