我正在使用下面的 aws cloudformation 模板来启动自动缩放组,当我尝试运行 cfn-init 时,它抛出一个 python 错误。我已经尝试了所有我能想到的方法来解决这个问题,但现在我完全陷入了困境。我得到的错误是:
构建期间发生错误:列表索引必须是整数,而不是 unicode
这是我的 Cloudformation 模板:

Type: String PublicSecurityGroup: Description: The security group for use with ec2. Type: String TargetGroup: Description: The load balancer target group Type: String Subnets: Description: The load balancer target group Type: 'List<AWS::EC2::Subnet::Id>' DomainUrl: Description: The url of the site excluding any sub domains eg.

任何帮助或引导正确的方向都会很棒。我尝试过使用不同版本的 aws-cfn-bootstrap,但它们都给了我同样的问题。
