owner_pw where we were expecting an input PDF filename, operation (e.g. "cat") or "input_pw"

Just checked the page of my local pdftk: Seems like above message wants to tell you that "owner_pw" is neither a pdf-filename nor an operation nor "input_pw". ("input_pw" obviously is special)

Try adding a command, e.g. simply "cat"

$doc->call_pdftk('apps.pdf', 'test.pdf', 'cat', 'owner_pw','abc12345');
