Pipe Doesn't Work on Output Kangaroo Geometry

Hi All, I have a weird problem. For some reason Pipe component doesn’t work on output geometry from Kangaroo. I tried to even bake the curves and perform pipe in rhino to no avail. Is there something I’m missing in that definition that causes this behavior ? Thanks!

There seems to be no problem with piping at the end?
