您可以将事件添加到您的模板。但对于S3 事件：

S3 存储桶名称。此存储桶必须存在于同一模板中。

因此，您的模板可以修改如下：

AWSTemplateFormatVersion: "2010-09-09"
Transform:  'AWS::Serverless-2016-10-31'
Resources:

  MyBucket:
    Type: AWS::S3::Bucket
    Properties:
      BucketName: test-bucket-3422344

  rData:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: functions/load_data     
      FunctionName: sample-function
      Handler: lambda_function.lambda_handler
      Runtime: python3.8
      MemorySize: 3008
      Timeout: 100
      Role: !Sub arn:aws:iam::${AWS::AccountId}:role/main_service_role
      Environment:
        Variables:
          bucket_name: sample-bucket
          file_name: config/test.csv
      Events:
        S3Event:
          Type: S3
          Properties:
            Bucket: !Ref MyBucket
            Events: s3:ObjectCreated:Put
