[Python] Trying to use Autofac in python 3.12 is triggering cannot be converted to type error

I'm tasked with converting some legacy python code to Python 3.12.Before it was using .DotNet to import .net dlls, not due to version contraints I'm using clr. However where the old code worked i'm having trouble resolving a SimpleJsonSerializer.

This is the error:

"Object of type 'System.RuntimeType' cannot be converted to type 'System.Collections.Generic.IEnumerable`1[Autofac.Core.Parameter]'."


That is being triggered by this code:

import clr
clr.AddReference(Autofac)
clr.AddReference(MyNamespace)

from MyNamespace import SimpleJsonSerializer
from System.Collections.Generic import List
import Autofac
from Autofac import ContainerBuilder
from Autofac.Core import Parameter

def setUpSerializer(self):
builder = ContainerBuilder()
container = builder.Build()

serializer_type = clr.GetClrType(SimpleJsonSerializer)
scope = container.BeginLifetimeScope()
registrations = container.ComponentRegistry.Registrations
empty_parameters = Parameter
serializer = registration.Activator.ActivateInstance(scope, empty_parameters)

for registration in registrations:
try:
registered_type = registration.Activator.LimitType
if registered_type == serializer_type:
serializer = registration.Activator.ActivateInstance(scope, empty_parameters)
break
except Exception as e:
print(f"Error inspecting registration: {e}")


Copilot has tied itself in a knot suggesting I use

empty_parameters = ListParameter
serializer = registration.Activator.ActivateInstance(scope, empty_parameters)


But ListParameter isn't definined anywhere and I don't know where to get it.

Any help is much appreciated.
