amazon-web-services - Waiter ChangeSetCreateComplete failed: Waiter 遇到终端故障状态

Question

我正在关注 CloudFormation 教程，这是我的 AWS CloudFormation 模板：

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Description: A starter AWS Lambda function.
Resources:
  helloworldpython3:
    Type: 'AWS::Serverless::Function'
    Properties:
      Handler: app.lambda_handler
      Runtime: python3.6
      CodeUri: src/
      Description: A starter AWS Lambda function.
      MemorySize: 128
      Timeout: 3
      Environment:
        Variables:
          TABLE_NAME: !Ref Table
          REGION_NAME: !Ref AWS::Region
      Events:
        HelloWorldSAMAPI:
          Type: Api
          Properties:
            Path: /hello
            Method: GET
      Policies:
        - DynamoDBCrudPolicy:
            TableName: !Ref Table

Table:
  Type: AWS::Serverless::SimpleTable
  Properties:
    PrimaryKey:
      Name: greeting
      Type: String
    ProvisionedThroughput:
      ReadCapacityUnits: 1
      WriteCapacityUnits: 1

我可以使用aws cloudformation package. 但是当我尝试使用 部署它时sam deploy，我从 shell 中得到了这个输出：

错误：等待创建变更集。错误：无法为堆栈创建变更集：hello-world-sam，例如：Waiter ChangeSetCreateComplete 失败：Waiter 遇到终端故障状态：对于表达式“状态”，我们匹配预期路径：“失败”状态：失败。原因：无效的模板属性或属性 [Table]

您的 YAML 格式不正确：

AWSTemplateFormatVersion: "2010-09-09"
Transform: "AWS::Serverless-2016-10-31"
Description: A starter AWS Lambda function.
Resources:
  helloworldpython3:
    Type: "AWS::Serverless::Function"
    Properties:
      Handler: app.lambda_handler
      Runtime: python3.6
      CodeUri: src/
      Description: A starter AWS Lambda function.
      MemorySize: 128
      Timeout: 3
      Environment:
        Variables:
          TABLE_NAME: !Ref Table
          REGION_NAME: !Ref AWS::Region
      Events:
        HelloWorldSAMAPI:
          Type: Api
          Properties:
            Path: /hello
            Method: GET
      Policies:
        - DynamoDBCrudPolicy:
            TableName: !Ref Table
  Table:
    Type: AWS::Serverless::SimpleTable
    Properties:
      PrimaryKey:
        Name: greeting
        Type: String
      ProvisionedThroughput:
        ReadCapacityUnits: 1
        WriteCapacityUnits: 1

Table应该在Resources. 使用像cfn-python-lint这样的 linter
