Could you please tell us the version of the ctrlX CORE - Motion, - IDE and - Python Runtime app you are using?
Please keep in mind that there are two ways of running a script. Like I mentioned in this post.

So the python interpreter running in your browser does probably not have the necessary sources to interpret the script. You will have to choose the option run in script interpreter for this case. Just tested this scenario again.
