Hello @ADCMHI,
your code contains syntax errors, you have index arguments after a keyword argument in your CallUVCommand call and you also refer to module attributes that do not exist in your script, uvw and cmdid. You also did not properly follow the code example I provided.
Your script could either be a product of some chat bot which is not knowing what is doing (but at least CoPilot/ChatGPT write better Cinema 4D code these days) or the struggles of a beginner. And while we understand that CoPilot is a useful tool (we use it ourselves) and that everyone has to start, we cannot help you with chatbot gibberish or with learning the basics of programming. See our Support Procedures for details.
I personally operate by the rule: "Newcomers have one free" and therefore fixed here your script for you. Please understand that we cannot help you with further questions that are on such a fundamental level of non-functional code. Please also understand that this is not a commitment of SDK to always provide solutions for newcomers, no matter in which state their code is.
Cheers,
Ferdinand
