amazon-web-services - AWS S3创建错误: "The event is not supported for notifications (Service: Amazon S3; Status Code: 400; Error Code: InvalidArgument"

Question

我正在 Code9 中开发我的第一个 lambda，它应该由 S3 事件触发。不幸的是，当我尝试部署时，我不断收到 CloudFormation 错误:

"The event is not supported for notifications (Service: Amazon S3; Status Code: 400; Error Code: InvalidArgument; Request ID: CF3108325F3C9B60; S3 Extended Request ID: wcWzRXUu7YJn/BVnPDtOx7yBHllhIPELEwsTweqVcfwLw1hkR2iDiSmQbxeL3Hrtp7Kv58ujS2s=; Proxy: null)"

请参阅以下来自 AWS Mgm 控制台的 CloudFormation 事件:

下面是我的 AWS SAM template.yaml 文件:

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Description: An AWS Serverless Specification template describing your function.
Resources:
  olatexOrdersInputDirectory:
    Type: 'AWS::S3::Bucket'
  olatexXlsxOrderLoader:
    Type: 'AWS::Serverless::Function'
    Properties:
      Handler: olatexXlsxOrderLoader/index.handler
      Runtime: nodejs12.x
      Description: ''
      MemorySize: 128
      Timeout: 15
      Policies:
      - AWSLambdaBasicExecutionRole
      - AmazonS3FullAccess
      - AmazonDynamoDBFullAccess
      Events:
        S3Event:
          Type: S3
          Properties:
            Bucket: !Ref olatexOrdersInputDirectory
            Events: S3:ObjectCreated:*

策略之后的行: 我添加了扩展 IAM 策略，因为我怀疑错误与权限不足有关，但它没有帮助。
下面我附加了从 SAM 的 template.yaml 生成的 CloudFormation 模板:

非常感谢您的帮助!

基于评论。

该问题是由使用 S3:ObjectCreated:* 而不是 s3:ObjectCreated:* 引起的。

S3 事件名称区分大小写。
