I do not understand the error message

Hi @ROxX ,

I think your python script file name that you specified in your setup.py under console_scripts is incorrect.
It should be of the following format:

"<desired_executable_name> = <ros2_package_name>.<python_script_file_name>:main",

I don’t know what you have typed in your setup.py file. I am assuming that you have put your class name in place of your python script file name. Therefore, your setup file did not detect/recognize your python file.

Please revise your setup.py file. That should solve your issue.

Regards,
Girish
