cadquery How to solve the error

How to solve the error in the picture? The specific content of the reference function is as follows: def bcc_heterogeneous_lattice(unit_cell_size, min_strut_diameter, max_strut_diameter, min_node_diameter, max_node_diameter, Nx, Ny, Nz, topology='bcc', rule='linear', position=(0, 0, 0), rotation=(0, 0, 0)): if topology not in ['bcc', 'bccz', 'sbcc', 'sbccz']: raise TypeError(f'The type '{topology}' does not exist!') min_strut_radius = min_strut_diameter / 2.0 max_strut_radius = max_strut_diameter / 2.0 if rule == 'linear': strut_radii = np.linspace(min_strut_radius, max_strut_radius, Nz) node_diameters = np.linspace(min_node_diameter, max_node_diameter, Nz) if rule == 'sin': average = lambda num1, num2: (num1 + num2) / 2 strut_radii = np.sin( np.linspace(min_strut_radius, max_strut_radius, Nz) * 12) + 2 * average(min_strut_radius, max_strut_radius) node_diameters = np.sin( np.linspace(min_node_diameter, max_node_diameter, Nz) * 12) + 2 * average(min_node_diameter, max_node_diameter) if rule == 'parabola': x = np.linspace(0, 1, num=Nz) frep = lambda d_min, d_max: -4 * d_max * (x - 0.5) * (x - 0.5) + d_max + d_min strut_radii = frep(min_strut_radius, max_strut_radius) print(strut_radii) node_diameters = frep(min_node_diameter, max_node_diameter) UC_pnts = [] for i in range(Nx): for j in range(Ny): for k in range(Nz): UC_pnts.append((i * unit_cell_size, j * unit_cell_size, k * unit_cell_size)) print("Datapoints generated") result = cq.Workplane().tag('base').transformed( offset=cq.Vector(position[0], position[1], position[2]), rotate=cq.Vector(rotation[0], rotation[1], rotation[2])) result = result.pushPoints(UC_pnts) unit_cell_params = [] for i in range(Nx * Ny): for j in range(Nz): unit_cell_params.append({"unit_cell_size": unit_cell_size, "strut_radius": strut_radii[j], "node_diameter": node_diameters[j], "type": topology}) result = result.eachpointAdaptive(unit_cell, callback_extra_args=unit_cell_params, useLocalCoords=True) print("The lattice is generated") return result
