Polyline error: solve inside cannot be set for an object that is excluded due to material threshold constraints

[robtrix]

Hello all,

I'm getting an error when trying to draw a polyline with Ansys Maxwell 3d.
On the terminal i get:
PyAEDT ERROR: AEDT GRPC API CALL ERROR on create_polyline
PyAEDT ERROR: Failed to execute grpc AEDT command: CreatePolyline
PyAEDT ERROR: File "c:\Work\995_Python\Start_Ansys\Ansys_start_env\pattern_drawing.py", line 117, in pattern_drawing
PyAEDT ERROR: m3d.modeler.create_polyline(test_points)

About the code, in the main.py where i do the import of all the needed packages, and i first setup the Maxwell 3d

m3d, setup_config = Maxwell_cfg.setup_Maxwell_3D(Maxwell3d,project_name)

#Draw the desired pattern
objects_list_m3d = pattern_drawing.pattern_drawing(m3d, Excel_input_data, Others_data_excel)

where

def setup_Maxwell_3D(Maxwell3d,project):

#Launch AEDT in non graphical mode and set the DC conduction solution type.

m3d = Maxwell3d(
            projectname=project,
            designname=project+"DCConduction",
            specified_version="2023.2",
            new_desktop_session=False,
            non_graphical=True,
            solution_type="DCConduction")

#Create the setup configuration
setup = m3d.create_setup()

#Setup settings
setup.props["MaximumPasses"] = 10
setup.props["MinimumPasses"] =  2
setup.props["MinimumConvergedPasses"] =  1
setup.props["PercentRefinement"] =  30
setup.props["SolveFieldOnly"] =  False
setup.props["PercentError"] =  1
setup.props["SolveMatrixAtLast"] =  True
setup.props["UseNonLinearIterNum"] =  False
setup.props["UseIterativeSolver"] =  False
setup.props["RelativeResidual"] =  1E-06
setup.props["NonLinearResidual"	] =  0.001

return m3d, setup

and

def pattern_drawing(m3d, input_data_excel,others_data_excel):
[omissis]
test_points = [["0mm", "0mm", "0mm"], ["100mm", "20mm", "0mm"],
["71mm", "71mm", "0mm"], ["0mm", "100mm", "0mm"]]
#m3d.modeler.create_polyline(vertices_with_square_brackets,close_surface=True)
m3d.modeler.create_polyline(test_points,close_surface=True)
return

The point is that if i run the example code by itself(reported below), the polyline is drawn correctly. I don't understand what i'm missing.

from pyaedt import Desktop
from pyaedt import Maxwell3d
desktop=Desktop(specified_version="2023.2", new_desktop_session=False)
aedtapp = Maxwell3d()
aedtapp.modeler.model_units = "mm"
modeler = aedtapp.modeler
test_points = [["0mm", "0mm", "0mm"], ["100mm", "20mm", "0mm"],
["71mm", "71mm", "0mm"], ["0mm", "100mm", "0mm"]]
P1 = modeler.create_polyline(test_points, name="PL_line_segments")

I have searched around for a similar problem, but i didn't find something similar to solve the issue.....

Thank you in advance!!!
