Cloudfront UpdateDistribution 操作因 ServiceUnavailable 而失败

Question

我正在尝试使用 Boto3 将 Origin 和 Behaviors 添加到现有的 CloudFront 分配，但它失败并出现以下错误，还添加了重试。 我尝试使用独立脚本和 CloudFormation 自定义资源，但都失败了。 之前在这里报告的相同问题： https://github.com/aws/aws-cdk/issues/15891#issuecomment-1243756855 ，有什么解决方法可以解决这个问题吗？

Traceback (most recent call last):
