Hi,
we are getting “An item with the same key has already been added” exception while upgrading the pdf file to PDF_A_2A format.
//code snippet//
var doc=sourceFilePath; // source file is in PdfFormat.v_1_7 format
doc.Convert(new MemoryStream(),PdfFormat.PDF_A_2A,ConvertErrorAction.Delete); // throwing the exception
Regards,
Kiran
