Argument #1 ($pdf_object) must be of type ddn\sapp\PDFObject, bool given

[Guervyl]

I'm getting this error: ddn\sapp\PDFDoc::add_object(): Argument #1 ($pdf_object) must be of type ddn\sapp\PDFObject, bool given, called in \vendor\ddn\sapp\src\PDFDoc.php on line 605 when trying to sign an already signed PDF.

Trace:

\vendor\ddn\sapp\src\PDFDoc.php:709 {▶}
  \vendor\ddn\sapp\src\PDFDoc.php:605 {▶}
  \vendor\ddn\sapp\src\PDFDoc.php:785 {▶}
  \vendor\ddn\sapp\src\PDFDoc.php:918 {▶}

So I check the code, it is returning false for the image that makes visible the signature (the existed one).

I changed this part to:

// Store the objects
        foreach ($updated_objects as &$object) {
            if(!is_bool($object)) { // Don't add if it's a boolean
                $this->add_object($object);
            }
        }

It works fine. The problem is that the PDF does not contain the first visible signature's image.
