[Ultimate PDF] Ultimate PDF | Getting an error Generating PDF

Hi, we are having this error generating the PDF:

It's OnPrem not OutSystems Cloud and this happens when we try to change the tmp folder to one created by us (this folder has write and read access to everyone).

The odd things is that the folder is being filled with files from Ultimate PDF, but we are getting that error and we can't see the generated PDF.

Bets Regards

HI @Frederico Lopes,

Check once whether you have the permission to insert files on the folder. This means you should verify whether the custom temporary folder you're using for Ultimate PDF has the correct file system permissions. 

Try generating a PDF with a very simple screen.

  • If that works → the problem is your content

  • If that fails → the issue is browser config, server setup, or permissions

  • Add console.log() or debugging steps to isolate the crash
  • Make sure its not due to Timeout

Hi Lavanya,

The folder that we created has public access, everyone can write and read from it.

The content is not the problem, when we use the server TMP folder, everything works.
