Python OpenStack SDK не возвращает имя хоста гипервизора ⇐ Python

[Anonymous]

Я написал клиентский код следующим образом.
# Get Hypervisor details
try:
print(f"+----------------------------------------------------------+")
print(f"| Hypervisor details |")
print(f"+----------------------------------------------------------+")
for hypervisor in conn.list_hypervisors():
print(f"Hypervisor is: {hypervisor}")
print(f"Hypervisor status: {hypervisor.status}")
print(f"Hypervisor vcpus: {hypervisor.vcpus_used}")
print(f"Hypervisor type: {hypervisor.hypervisor_type}")
print(f"Hypervisor id: {hypervisor.id}")
print(f"Hypervisor state: {hypervisor.state}")
print(f"Hypervisor host IP: {hypervisor.host_ip}")
print(f"Hypervisor running VMs: {hypervisor.running_vms}")
print(f"Hypervisor running VMs: {hypervisor.vcpus}")
print(f"Hypervisor hostname: {hypervisor.hypervisor_hostname}")

print(f"")
except EndpointNotFound as exp:
print("Error: {}".format(exp))
print(f"")

Когда я печатаю сам объект «гипервизор», я вижу следующие детали (я отформатировал их для удобства чтения).
openstack.compute.v2.hypervisor.Hypervisor

Большинство значений выводятся, как показано ниже, однако когда я пытаюсь получить доступ к «hypervisor.hypervisor_hostname», выдается исключение.
