Adding polygon prevents (instant crash) mesh viewing

[ASLOBEAR]

I'm using a list of points to create a polygon, but the mesh can not be viewed and crashes the CSXCAD viewing app

CSX = Continuous Structure()
material = CSX.AddMetal('PEC')
pset = CSX.GetParameterSet()
value = [(0, 0), (0, 1), (1, 1), (1, 0), (0, 0)]
poly=CSXCAD.CSPrimitives.CSPrimPolygon(pset, material, value, norm_dir=2, elevation=elevation)
poly.SetPriority(10)

Is there anything I can do to further debug the root cause of my issue?

@ASLOBEAR This is how I create polygons using AddLinPoly:

TopMetal1 = CSX.AddMaterial('TopMetal1', kappa=2.78E7)

pts_x = np.array([])
pts_y = np.array([])
pts_x = r_[pts_x, 22.200]
pts_y = r_[pts_y, 0.000]
pts_x = r_[pts_x, 34.200]
pts_y = r_[pts_y, 0.000]
pts_x = r_[pts_x, 34.200]
pts_y = r_[pts_y, 57.000]
pts_x = r_[pts_x, 22.200]
pts_y = r_[pts_y, 57.000]
pts = np.array([pts_x, pts_y])
TopMetal1.AddLinPoly(priority=200, points=pts, norm_dir ='z', elevation=TopMetal1_zmin, length=TopMetal1_thick)

As you can see, there are only 4 points specified, and there is no need to close the polygon by going back to the starting point.
