We are seeing an error Aspose.Pdf.InvalidPdfFileFormatException - Startxref not found when trying to concatenate PDF files. PDF file does open, is not corrupt. The issue only happens in production and is not reproducible. I understand you guys can’t help without having a way to reproduce but if you can provide any pointers on when this error occurs? What is “startxref not found?” Since we are not able to reproduce locally and ASPOSE.PDF is a blackbox to us, we can’t really get to the bottom of the issue.
