code：

import cadquery as cq
from lq.topologies.schwartz import schwartz_p_heterogeneous_lattice
cq.Workplane.schwartz_p_heterogeneous_lattice = schwartz_p_heterogeneous_lattice

# BEGIN USER INPUT
unit_cell_size = 4

Ny = 10
Nz = 10
min_thickness = 0.1
max_thickness = 7
# END USER INPUT

schwartz = schwartz_p_heterogeneous_lattice(unit_cell_size, min_thickness, max_thickness,
                                      Nx, Ny, Nz
                                      )

Error：

@binfengjiao There is a lot of code that we cannot see, so it makes it impossible to help. Can you post a minimal example that reproduces the issue?
