Just a quick tip. I'm pretty experienced with Node, but only slowly getting into ESM/import style syntax. As more and more NPM packages start requiring it, I'm finding myself using it more and more as - well, I'm forced to. So as just a general FYI, our Node SDK can be imported just fine:
import PDFServicesSdk from '@adobe/pdfservices-node-sdk';
No big deal and this is expected, but as it worried me a bit until I saw it worked, I wanted to share with the rest of yall.
