Hi, I have some signed PDFs that can not be signed again with this tool.

Error info at C:\\xampp7\\htdocs\\webapp\\htdocs\\custom\\vendor\\ddn\\sapp\\src\\PDFUtilFnc.php:637: object is not valid: 18

The PDF is an invoice so I can't upload it here.

You will have to upload the file, because if you paste only a text the PDF cannot be generated, bytes may be lost
