I am creating QR bar code as defined in doc1678110.1.  I can get the QR code to work in reports builder but when I run it from a URL I get this message:  REP-1401: A fatal PL/SQL error occurred in program unit qr_codeformula. ORA-39565: Message 39565 not found;  product=RDBMS; facility=ORA

here is the report formula.

function qr_codeFormula return varchar is

  image_file_name VARCHAR2(1000);

begin

  image_file_name := SRW.CREATE_TEMPORARY_FILENAME ;

  qrcode.generate (:pdf417 , image_file_name);

  return(image_file_name); 

end;

Any assistance would be appreciated.
