AttributeError("'numpy.ndarray' object has no attribute 'name'")

I intend to execute example at github page of pyg4ometry module https://github.com/g4edge/pyg4ometry.
```
import pyg4ometry as pg4
from g4edgetestdata import G4EdgeTestData

g4data = G4EdgeTestData()
# define a geometry registry
reg = pg4.geant4.Registry()

# build the world volume
world_s = pg4.geant4.solid.Orb("WorldAir", 1.5, reg, lunit="cm")
world_l = pg4.geant4.LogicalVolume(world_s, "G4_AIR", "WorldAir", reg)
reg.setWorld(world_l)

# import an STL file
reader = pg4.stl.Reader(g4data["stl/utah_teapot.stl"], registry=reg)
teapot_s = reader.getSolid()

# place the teapot in the world
teapot_l = pg4.geant4.LogicalVolume(teapot_s, "G4_Cu", "UtahTeapot", reg)
pg4.geant4.PhysicalVolume([0, 0, 0], [0, 0, 0], teapot_l, "UtahTeapot", world_l, reg)

# export to GDML file "geometry.gdml"
writer = pg4.gdml.Writer()
writer.addDetector(reg)
writer.write("./geometry.gdml")

# start an interactive VTK viewer instance
viewer = pg4.visualisation.VtkViewer()
viewer.addLogicalVolume(reg.getWorldVolume())
viewer.view()
```

For PyCall i create virtual environment with pyg4ometry and pybdsim installed. No ROOT usage is required. PyCall is then build with python executable from that environment.
I replace the first 3 lines with
```
pg4 = pyimport("pyg4ometry")
g4etd = pyimport("g4edgetestdata")
g4data = g4etd.G4EdgeTestData()
```
Executions breaks at line
```
writer.addDetector(reg)
```
with
```
