Hello,
Occasionally our calls to the EO.PDF.PdfDocument(Stream stream) constructor will throw a null reference error. This does not happen in every call. It only seems to happen when images are being merged into the PDF stream. Not every image triggers this error. Currently we do not have a sample image we can share due to PII restrictions.
Stack trace:
System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.
Source=EO.Pdf
StackTrace:
at EO.Internal.nmba.hoxn(PdfDocumentSecurity cwr)
at EO.Internal.nmba.rxxw(Boolean cwo, Boolean cwp, PdfDocumentSecurity cwq)
at EO.Internal.nmap.xhkq(Stream csb, Boolean csc, Boolean csd)
at EO.Internal.nmap..ctor(Stream cro, PdfDocumentSecurity crp, Boolean crq, Boolean crr)
at EO.Internal.nmap..ctor(Stream crs, PdfDocumentSecurity crt)
at EO.Pdf.PdfDocument..ctor(Stream stream)
at [Our code redacted]
Current version: 20.3.63
Google Chrome is able to render the input stream for the EO.Pdf constructor as a PDF document.
Thank you

Our development team was able to reproduce the error without using PII data and images. Is there a way I can securely upload these files for the EO team?
Thank you

Hi,
We have looked into the file. The root of the problem is in this file there is a chunk of corrupted data. We will change our code to skip this chunk of data in our next build so that it will still be able to read the file without crashing with an exception.
Thanks!
