Hello everybody. I will appreciate any help. I have faced an issue with workflow step 'Convert to PDF/A':

I have no ideas what is a reason and how to investigate the issue.

What is the source of this PDF?

Is it the only PDF that fails, or are all the PDFs failing (you may want to check the workflow settings)?

Also, can you convert the PDF to the desired format using Acrobat? If yes, please share the PDF with me for a quick test to verify the case with Forms' internal libraries.
