Ok. I was doing it this way at the very beginning. That was the point when I get this error:
Both try to make a script through UI or create it from file. Same result. If I get the same error, what should I check?
I guessed that Jhyton Scripting set up and new JSS Scripting have conflict, pls bear in mind that I use Ivan’s Helper Libraries: Ivan’s Helper Libraries - OH3, Python, JavaScript
