Appreciated the answer, Enrico.

Your analysis really hit it. We uninstalled the python-barcode and pillow package from each of the os user: irisowner/irisusr/root. And only re installed them in root user. It works.

Regards the embedded python. Because the python script was wrote and run in a early IRIS version. So we re use the same way. I think it's good idea to use embedded python from IRIS2022.

Appreciated the help @Jeffrey Drumm   @Julian Matthews  @Alex Woodhead . It seems that we need the third-part tool to achieve this.
 

Thank you Jacques.
