如何解决接收到检测到的验证错误：值 '[AWS:RDS::DBInstance]' at 'typeNameList' 失败

我正在尝试创建一个运行 MysqL 数据库的 RDS 服务器并收到以下错误：

1 validation error detected: Value '[AWS:RDS::DBInstance]' at 'typeNameList' Failed to satisfy constraint: Member must satisfy constraint: [Member must have length less than or equal to 204,Member must have length greater than or equal to 10,Member must satisfy regular expression pattern: [A-Za-z0-9]{2,64}::[A-Za-z0-9]{2,64}(::MODULE){0,1}]

解决方法

缺少冒号。应该是 AWS::RDS::DBInstance
