An error was encountered while processing the file. Some feature might not work.

Question

Hello,

We have implemented the PDF embed API into our site for users to view PDF documents which are stored in AWS S3. But we have a few files which generate the error: An error was encountered while processing the file. Some feature might not work.

I have checked the pdf files in question, but they appear to be fine. I can also open them in Acrobat reader and other pdf readers.

I have uploaded one of the files into the demo website and it also shows this error. Is there anything that can be done to show these pdf files correctly in the viewer? Unfortunately, I cannot share the files publicly, as the PDF documents in question contain confidential information. If I edit the PDF to mask the confidential information, the edited file is shown correctly... soo

Thanks!

We use Datalogic PDF checker for other purposes, but I have checked the faulty PDF and attached the result. The only error given was about embedded fonts. Could this cause the issue?
