Hi there,

Please try the steps posted [here](https://pdfjs.community/t/pdf-js-express-viewer-watermarks/1614) and let me know if you can get it resolved.

Additionally, could you provide me with the following:

- The exact error message you are seeing
- If possible, a link to a staging site where I can reproduce/see the issue

Thanks!  
Logan
