AttributeError: 'Location' object has no attribute 'region'

Has not been updated to be 2.x compatible since it is referencing region.

Steps to Reproduce

1. Run ServiceNow job

@itdependsnetworks I'm guessing "ServiceNow 2.X fails" means "ServiceNow SSoT Integration needs to be made compatible with Nautobot 2.X", not "ServiceNow SSoT Integration needs to be made compatible with ServiceNow 2.X"

We should add developer docs on how to setup a ServiceNow instance for testing or at least how to access an existing ServiceNow instance.
