Amazon web services cnf init在ubuntu ami上抛出Python错误

我正在使用下面的aws cloudformation模板来启动一个自动缩放组，当我尝试运行cfn init时，它抛出了一个python错误。我已经想尽一切办法来解决这个问题，但现在我完全被难倒了。我得到的错误是：

生成期间发生错误：列表索引必须是整数，而不是unicode

这是我的Cloudformation模板：

在正确的方向上提供任何帮助或指导都将是了不起的。我尝试过使用不同版本的aws cfn引导，但它们都给了我相同的问题。

我对UserData做了以下更改，将获得最新的cfn init
