Error. Server returned unexpected HTTP status: 400

Hi, I’m getting the error above when trying to annotate PDFs. It repeatedly shows up, filling up the whole screen, if not closed.

I’m not sure, but it seems that this is only happening for PDFs that I have added to Paperpile on the last week or so. Older PDFs do not show the message.

Let me know how can I help to debug it!

Best
