PdfDocument.Merge causes Invalid/Unknown/Unsupported format error

[Alexei Tolkachev NO LONGER WITH COMPANY]

I am using Essential PDF to merge two and more PDF files. It worked fine in testing with the PDF files made available to me, however, after I started testing with the PDFs produced by Oracle Documaker (for which my solution is intended)m, I get the following error every time when trying to execute PdfDocument.Merge

Message ==Invalid/Unknown/Unsupported format
Data ==System.Collections.ListDictionaryInternal
InnerException ==
TargetSite ==Byte[] PostProcess(Byte[], System.String)
StackTrace == at Syncfusion.Pdf.Primitives.PdfStream.PostProcess(Byte[] data, String filter)

at Syncfusion.Pdf.PdfDocumentBase.Append(PdfLoadedDocument ldDoc)
at Syncfusion.Pdf.PdfDocumentBase.Merge(String[] paths)

Are there any compatibility setting I need to be looking at either on the Essential PDF component or the PDF generator?

I can e-mail the file that fails to the Syncfusion support personnel if requested.

Thanks!

Hi,

Thank you for your interest in Syncfusion products.

I am afraid that I am unable to reproduce the issue "while merging the PDF document it throwing an exception". Could you please send you PDF documents which you trying to merge to us? It would be helpful for us to reproduce the issue and provide a possible solution.

Best Regards,
Bhuvana
