Detailed description of issue

On April 15, 2024 at UTC, a watermark appeared on a PDF for an hour or two starting around 10:00 am.

I did nothing and after a while the PDF watermark disappeared.

Was the license server unstable?

Hi there,

Are you able to provide any network logs at the time? Can you see if any of the requests are failing?

At the time, “https://auth.pdfjs.express/?key=xxx” returned a 200 response, but the PDF had a watermark.

Currently, the PDF has no watermark and displays correctly.
Therefore, it is not logged.

I thought it was an effect of the license server as it resolved itself over time.
Could you please investigate if the server is the problem?

I can confirm the occurrence again and will post the log.

Hi there,

We have not found any server failures on our end.

You will need to create a rest API key. You are currently using your license key as your API key.

Please see this guide: PDF.js Express Utility API | Documentation

Darian

Thanks for confirming.

Why do I need a REST API key?

Since the Utility API is not used, I think license key is fine.

Could you let us know what features you are currently using? Are you using Express Viewer or Plus?
