Assertion error after we Attach documents to the Adobe form

Hello Experts,

An Assertion error is thrown after we perform any action after we have attached any document in the interactive form .

The assertion is at the following line:

if l_submit_type = `pdf`.                           "#EC NOTEXT

          assert /1wda/dinteractive_form_zci~mv_content_type = `application/pdf`. "#EC NOTEXT

           "Moving the PDF to PDF_SOURCE is independent from the availability of DATA_SOURCE but vital for the PDFOnly use case!

           /1wda/dinteractive_form~mv_pdf = /1wda/dinteractive_form~mv_request_data.

         endif.

Below are the screenshots of ST22 dump.

Please suggest some solution.

Thanks !

Regards,
Sanket.
