如何使用google.api_core.operations_v1.AbstractOperationsClient获取长时间运行的操作

Question

我用下面的代码创建了一个新的磁盘：

disk_client = compute_v1.DisksClient()
request = compute_v1.InsertDiskRequest(project=PROJECT, zone=ZONE,disk_resource=disk)
operation = disk_client.insert(project=PROJECT, zone=ZONE, disk_resource=disk)

通过gcloud我可以看到我的操作：

gcloud compute operations describe operation-1711690161380-614c5ec08dd85-8f424625-2dfb72a1 --zone europe-west3-b

在另一个脚本中，我想用google.api_core.operations_v1.AbstractOperationsClient这个类来获取长时间运行的操作的结果，但总是返回一个凭证问题！

这是我的代码：

os.environ['GOOGLE_APPLICATION_CREDENTIALS']="..\\..\\my-service-account.json"

name = f"projects/{PROJECT}/zones/{ZONE}/operations/operation-1711690161380-614c5ec08dd85-8f424625-2dfb72a1"

credentials, projectId = google.auth.default() 
print("credentials service account: ", credentials.service_account_email)
options = ClientOptions(api_endpoint="compute.googleapis.com/compute")
operation_client = AbstractOperationsClient(credentials=credentials, client_options=options)
operation = operation_client.get_operation(name)

但是我遇到了以下错误：

我使用的是同一个服务账号来创建磁盘和获取操作，你能帮我吗？

谢谢
