I tried to use the pipe component with a list of lines but something goes wrong

Hi,

When I tried to use the pipe component with a list of lines something went wrong and grasshopper crashed. I couldn't figure out how to fix it. Is it possible for somebody to look at my project and give me some feedback if you have a chance? This is the file ivanova_elitza_project_02.gh The part with the problem is marked in red.
