CST - Python API result view

Hello there Simulia Community,

Here I am trying to do a very simple task given in the example of CST Studio Suite  python API. As you can see the run id consists of 0, 1 and 2 where I am using the interactive mode and can see the results in the GUI. Yet the api does not provide the data when the get_result_item() is called. I feel like I am missing a simple step. I also tried non-interactive mode and the schematic view results also gives the same error.
