AWS S3创建错误：“通知不支持该事件服务：Amazon S3；状态代码：400；错误代码：InvalidArgument”

如何解决AWS S3创建错误：“通知不支持该事件服务：Amazon S3；状态代码：400；错误代码：InvalidArgument”

我正在Code9中开发我的第一个lambda，它可能是由S3事件触发的。不幸的是，当我尝试进行部署时，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:*

我在Policies:之后添加了几行，以扩展IAM策略，因为我怀疑错误与特权不足有关，但无济于事。
在下面，我将附加从SAM的template.yaml生成的CloudFormation模板：

非常感谢您的帮助！

基于评论。

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

S3事件名称是区分大小写的。
