I get this error when using the Syncfusion.Pdf.PDFDocument.Append() method.

"Invalid/unknown/unsupported PDF format. There is no endstream operator."

This error occurs regularly only with PDFs we receive from a certain company. Error does not occur with any other PDFs. However the problematic PDFs open fine in any PDF reader.

Hi Perry,

Thank you for using Syncfusion product.

Could you please send us the sample PDF file, which produces the issue?

It will be helpful for further investigation.

With regards,
