Aitbouhou, as promised earlier, we have included the fix for the reported issue with “NullReferenceException throws while converting a Word document to PDF with fields” in our latest weekly NuGet release (v28.1.35).

Root cause of the issue:
The input document contains fields within text boxes located in the footer. During the Word to PDF conversion, we mistakenly set the layout information of the fields to null, which resulted in the reported issue.
