我正在尝试将我的CloudFormation模板部署到其他区域进行测试。我的模板通过Boto3与us-east-1很好地配合使用，但如果它尝试其他区域，我不会得到错误输出。
在尝试不同的地区时，我意外地收到一封电子邮件，说加拿大地区已经过验证，但由于通过Boto3尝试，一直没有成功。(计费控制台显示所有地区现已激活(
我正在从Lambda(无专有网络(运行Boto3，它已使用Zappa部署到us-east-1。它的IAM策略没有指定特定的地区。
Python:
cf_client = boto3.client(
'cloudformation', region_name=request.POST['region'])
cf_client.create_stack(
StackName=stack_name,

从选择堆栈模板-AWS CloudFormation:
Amazon S3 URL:URL必须指向一个最大大小为460800字节的模板，该模板存储在您有读取权限的S3存储桶中，并且与堆栈位于同一区域。
我怀疑您的堆栈失败了，因为模板位于AmazonS3存储桶中，而该存储桶与启动堆栈的区域不同。您需要将模板复制到同一区域的bucket中，然后在create_stack()命令中提供它。
您可以使用AWS控制台启动模板来测试这一点，而不必通过boto3。
