Fn :: GetAtt的无服务器CloudFormation模板错误实例引用了未定义的资源

Question

我正在尝试设置新的存储库，但不断出现错误

The CloudFormation template is invalid: Template error: instance of Fn::GetAtt 
references undefined resource uatLambdaRole

在我的理想阶段，但是格式完全相同的开发阶段效果很好。

对于每种环境，我都有一个资源文件。

dev

devLambdaRole:
  Type: AWS::IAM::Role
  Properties:
    RoleName: dev-lambda-role # The name of the role to be created in aws
    AssumeRolePolicyDocument:
      Version: '2012-10-17'
      Statement:
        - Effect: Allow
          Principal:
            Service:
              - lambda.amazonaws.com
          Action: sts:AssumeRole
    ManagedPolicyArns:
      - arn:aws:iam::aws:policy/AWSLambdaFullAccess
      #Documentation states the below policy is included automatically when you add VPC configuration but it is currently bugged.
      - arn:aws:iam::aws:policy/service-role/AWSLambdaVPCAccessExecutionRole

uatLambdaRole:
  Type: AWS::IAM::Role
  Properties:
    RoleName: uat-lambda-role # The name of the role to be created in aws
    AssumeRolePolicyDocument:
      Version: '2012-10-17'
      Statement:
        - Effect: Allow
          Principal:
            Service:
              - lambda.amazonaws.com
          Action: sts:AssumeRole
    ManagedPolicyArns:
      - arn:aws:iam::aws:policy/AWSLambdaFullAccess
      #Documentation states the below policy is included automatically when you add VPC configuration but it is currently bugged.
      - arn:aws:iam::aws:policy/service-role/AWSLambdaVPCAccessExecutionRole

在我的serverless.yml中，我的角色定义为

role: ${self:custom.stage}LambdaRole

并将舞台设置为

custom:
  stage: ${opt:stage, self:provider.stage}

运行serverless deploy --stage dev --verbose成功，但是运行serverless deploy --stage uat --verbose失败，并显示错误。谁能看到我在做什么错？直接从开发人员那里复制了uat资源，只更改了阶段名称。

这是资源文件所在目录的屏幕快照

Answer 1

我错过了将配置的关键部分复制到我的资源文件的实际参考中

resources:
  Resources: ${file(./serverless-resources/${self:provider.stage}-resources.yml)}

问题是我复制了指南中的内容，并熟练使用了self:provider.stage而不是self:custom.stage。当我更改此设置后，便可以部署它。

Answer 2

在此处结束时出现相同的错误消息。我的问题最终是我倒退了serverless.yml中的“资源”和“资源”键。

正确：

resources:       # <-- lowercase "r" first
  Resources:     # <-- uppercase "R" second
    LambdaRole:
      Type: AWS::IAM::Role
      Properties:
         ...
