hi again,

I was trying to analyze a .knxproj as the example in the repo says but this error comes out, could someone help me please? I don't know which list the exception refers to

I guess it was never tested on Windows. Maybe open an issue in the according repo reporting the bug en detail.

thanks you.

update:
after tracing the exception I could see that after line 29 the code flow goes directly to the line 35 and does not execute line 30, 31, 32, 33 and 34. I have no idea why. Perhaps for this reason it is that it is about accessing an index that does not exist and the exception is thrown. I'm using a .knxproj that i downloaded here ->https://www.theben.de/service-en-gb/ets-project-examples/ (all the examples work the same way) I appreciate any help.

Running it in a normal shell would show you a proper traceback.
The Theben test-project has no building schema defined. xknxproject seems to expect one.
But this is the wrong repository to discuss this...
