deploy serverless

Com esse código, serverless.yaml

org: titiura
app: api-lambda
service: api-lambda
frameworkVersion: '3'

provider:
  name: aws
  runtime: nodejs18.x
  iam:
    role:
      statements:
        - Effect: Allow
          Action:
            - s3:GetObject
          Resource:
            - arn:aws:s3:::alunos-csv/*

functions:
  cadastrarAlunos:
    handler: src/cadastro_batch/aws/index.cadastrarAlunos
    events:
      - s3:
          bucket: alunos-csv
          event: s3:ObjectCreated:*
          rules:
            - suffix: .csv

  simulandoUploadDoCsv:
    handler: src/cadastro_batch/local/index.simulandoUploadDoCsv
    events:

  cadastrarAlunosDoBucketLocal:
    handler: src/cadastro_batch/local/index.cadastrarAlunosDoBucketLocal
    events:
      - s3:

            - suffix: .csv
    enabled: false
  
plugins:
  - serverless-offline
  - serverless-s3-local
  - serverless-disable-functions

eu tenho esse erro no terminal :

Error:
CREATE_FAILED: S3BucketAlunoscsv (AWS::S3::Bucket)
alunos-csv already exists

O que pode ser esse erro?
