Some signed documents can't be signed again

[Daviid-P]

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
Warning info at C:\\xampp7\\htdocs\\webapp\\htdocs\\custom\\vendor\\ddn\\sapp\\src\\PDFDoc.php:972: root object does not exist, so cannot get information about pages

Error info at C:\\xampp7\\htdocs\\webapp\\htdocs\\custom\\vendor\\ddn\\sapp\\src\\PDFDoc.php:714: could not generate the signed document

Here's the PDF's cat, I deleted everything between >>stream XXXXXX endstream

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

[parallels999]

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