toggle_visibility & set_color returning error message

[parhasard]

Hi

I get this error message when I try to toggle visibility of items in the IFC file:

Traceback (most recent call last):
File "", line 22, in
File "ifcopenshell\geom\app.py", line 515, in toggle_visibility
File "ifcopenshell\geom\app.py", line 505, in toggle
File "ifcopenshell\geom\app.py", line 511, in visibility
File "OCC\Core\AIS.py", line 5230, in Erase
TypeError: in method 'AIS_InteractiveContext_Erase', argument 2 of type 'opencascade::handle< AIS_InteractiveObject > const &'

Additionally, 'viewer' object seems to be missing some attributes like 'set_color', get_selection_set'. ("highlight all selected products" in the snippets as an example)

Best Regards
Hazar
