      artifact: ETL/artifacts/ETL.zip
    events:
      - existings3: 
          bucket: xyz-bi
          event: s3:ObjectCreated:*
          rules:
            - prefix: log/LAMBDA_INVOKE_TEST/
     
-----------------

 iamRoleStatements:
        - Effect: Allow
          Action:
          - 's3:*'
          - 's3:ListAllMyBuckets*'
          - 's3:HeadBucket*'
