所以我正在尝试初始化一个现有的"react-ts"放大项目，该项目配置了大约 8 个服务。 当我运行放大推送时，一切似乎都很好且成功，除了以下情况，我收到此错误：
Resource Name: 2021/10/08/[$LATEST]c1c602b361e347ad83d49f77293e6aae (Custom::LambdaCallout)

我尝试创建角色"snsb927798344500-stage"并添加所需的策略，但是一旦我尝试重新运行amplify push命令，我就会收到一条错误消息，说snsb927798344500-staging already exist。 所以我认为是放大在每次推送时创建角色，并在过程失败后将其删除。这就是我在推送过程后无法再次看到"snsb927798344500-暂存"角色的原因。
该特定消息似乎与 CLI 上的此 GitHub 问题有关：https://github.com/aws-amplify/amplify-cli/issues/8363
我们今天遇到了同样的问题，下面为我们修复了它。
此处复制的解决方案：
此问题是由于 MFALambda 角色中缺少策略，该策略已在 #7729 中修复。您能否尝试将以下策略添加到您的身份验证云形成中，看看是否可以解决问题。需要添加的部分是名称为 corecocf3573d0_sns_pass_role_policy
的策略
