Merge PDFs

I have a workflow that creates a dataset and will run a template report to fill in with data from an SQL database and output a pdf. It then selects a url to a pdf from another database. I would like to merge the two so that the report is the first two pages of the pdf and the document is the third page.

 

I think I have everything set up correctly, but I am encountering this error:

 

 

Cannot handle iref streams. The current implementation of PDFsharp cannot handle this PDF feature introduced with Acrobat 6.

 

 

I found this 2016 answer: https://support.geocortex.com/customer/apex/essentialsGSCForumDetail?sub-nav=forum&main-nav=essentials&id=0D5f200006aOfOLCA0

 

 

I did download a PDFsharp package that contained version 1.51.5185-beta. I compiled it in Visual Studio to get the pdfsharp.dll. I'm not entirely sure I put it in the correct location.

 

 

I am using Workflow Designer 4.11.0.94. I'm not sure when we'll get everything upgraded, so I'm trying to make this work.

 

 

Any assistance or workarounds would be appreciated.
