Question

我试图了解无服务器的工作方式。我已经阅读了许多他们的文档/教程，但是当我到达要构建特定对象（如RDS实例）的那一部分时，对于MVP的外观我没有任何参考框架。

我发现这个Q/A post展示了站起来RDS实例的基础知识。我换出该区域换了一个比较本地的区域，然后尝试了一下：

service: sandbox
app: sandbox
org: # omitting

  name: aws
  runtime: nodejs12.x

  Resources:

            IpProtocol: tcp

            ToPort: 3306
        VpcId: 
            Ref: Vpc

当我尝试使用无服务器部署它时，出现以下错误： The CloudFormation template is invalid: Template format error: Unrecognized resource types: [AWS:EC2::VPC, AWS::RDS:DBInstance]

我可以看到这些资源存在于AWS上：

那么...这个错误是什么意思？我在做什么错了？

Answer 1

您的资源类型中有错别字。在这两种情况下，您都有一个冒号（:)，而您应该有一个双冒号（::）

Answer 2

如果您收到错误 Unrecognized "Resource Types"，则表示您的代码存在语法问题。

检查“无法识别的资源类型”后是否有错别字：

Unrecognized resource types: [AWS::Dynamo::Table]

在这种情况下，应该是

Type: AWS::DynamoDB::Table

无法识别的资源类型
