Sometimes I'm getting this error The file is not a valid PDF document. when trying to generate and download a PDF file, this has happened on several ocasions and sometimes if 2 users are trying to generate a pdf (different files) one gets the error and the other gets the PDF without any issues. 

Is this a known error or is there any solution that I'm might not be seeing?

Rank: #2

That error usually means the PDF is empty. Note sure what could cause this.

In this case the assign before has the URL and if I check the URL in the browser I get the page that should be in the PDF. 

In addition I'm also getting this error on Service Center
