尝试通过python中的AWS CDK创建预算时出现jsii错误

我正在尝试通过AWS CDK创建预算。

这是代码，它们是通过参考官方文档和执行类似操作的TypeScript解决方案拼凑而成的。

email = '[email protected]'
value = 90.0
subscription = sns_sub.EmailSubscription(email)
topic = sns.Topic(self, id='notification_topic', display_name='budget notifications',
                          topic_name='budget_notifications')
topic.add_subscription(subscription)
budget_data_props = aws_budgets.CfnBudget.BudgetDataProperty(budget_type='COST', time_unit='MONTHLY', 
                                                             budget_name='CDK budget',
                                                             budget_limit=aws_budgets.CfnBudget.SpendProperty(amount=value, unit='USD'))
np = aws_budgets.CfnBudget.NotificationProperty(comparison_operator='GREATER_THAN',
                                                notification_type='FORECASTED', threshold=90.0,
                                                threshold_type='PERCENTAGE')
sub = aws_budgets.CfnBudget.SubscriberProperty(address=topic.topic_arn, subscription_type='SNS')
nws = aws_budgets.CfnBudget.NotificationWithSubscribersProperty(notification=np, subscribers=[sub])

budget_props = aws_budgets.CfnBudgetProps(budget=budget_data_props, notifications_with_subscribers=nws)
budget = aws_budgets.CfnBudget(self, 'cdk budget', budget=budget_props)

我得到的错误是：

我使用的是带有类型提示的IDE，所以我对这似乎是类型不匹配的情况感到困惑。
