KiCad StepUp: The Sketcher for Footprint generation

I get some python error when generating footprint. I have one complex pad and it seems that if I delete it footprint is generated, but with it, there is error. Could you look if I’m doing something wrong?

Edit: I can’t get error text because it shows briefly in freecad window bottom line, and only part of it.
