Python 3.12 compatibility issue: TypeError: Meta.__new__() got an unexpected keyword argument 'engine'

[laramirez]

Hello,

Following my previous issue, I can confirm that I get the TypeError only when using Python 3.12 and not Python 3.11.

for firewall_cluster in FirewallCluster.objects.all():
     for physical_interface in cluster_firewall.physical_interface.all():
         if physical_interface.is_primary_mgt:  # this triggers the error (in 3.12 only, otherwise works fine)

TypeError: Meta.__new__() got an unexpected keyword argument 'engine'

Could it be a serialization issue?

Could not reproduce using python version:

agrant@dev-vm:~/PycharmProjects/smc-python/.venv1/bin$ ./python --version
Python 3.12.8

code:

for firewall_cluster in FirewallCluster.objects.all():
    for physical_interface in firewall_cluster.physical_interface.all():
        if physical_interface.is_primary_mgt:  # this triggers the error (in 3.12 only, otherwise works fine)
            logging.info(f"{firewall_cluster} - {physical_interface} is primary address")

got:

...

Can you send the full Traceback ?
