ADDITIONAL INFORMATION

new_hostvars = dict(
            # (...)
            vmss=dict(
                id=self._vmss['id'],
                name=self._vmss['name'],
            ) if self._vmss else {},
            # (...)
        )
        # (...)

        if len(self.nics) == 0:
            # Set the attribute information related to the Uniform VMSS instance
            # Set os compute name, os name, os version and hyper V generation
            resource_group = new_hostvars['resource_group']
            vmss_name = new_hostvars['vmss']['name']

Is failing if len(self.nics) == 0 and self._vmss is None
