无服务器部署返回存储桶已存在

Question

我有一个无服务器功能，用于将图像上传到离线工作的预先存在的存储桶中，但当我尝试并部署时，我要么得到...

An error occurred: ImageUploadBucket - MYUNIQUEBUCKET already exists.或An error occurred: IamRoleLambdaExecution - imageupload-dev-us-east-1-lambdaRole already exists.，即使我正在将我的函数部署到eu-west-1.

这是我的YML。

...  
  iamRoleStatements:
    - Effect: "Allow"
      Action:
        - "s3:*"
      Resource: "arn:aws:s3:::MYUNIQUEBUCKET/*"
  environment:
        region: eu-west-2
        imageUploadBucket: ${self:custom.imageUploadBucket}

custom:
    region: eu-west-2
    bucketName: MYUNIQUEBUCKET
    imageUploadBucket: MYUNIQUEBUCKET
    serverless-offline:
        httpPort: 3001

plugins:
    - serverless-offline

functions:
  newImageUpload:
        handler: ImageUpload.requestUploadURL
        events:
            - http:
                path: image-upload
                method: POST
                cors: true
            - s3:
                bucket: MYUNIQUEBUCKET
                event: s3:ObjectCreated:*
                existing: true

resources:
  Resources:
    ImageUploadBucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: MYUNIQUEBUCKET
        AccessControl: PublicRead
        CorsConfiguration:
        ...  

如果有任何建议，我将不胜感激。

存储桶和IAM角色和权限是全局的，这就是它们存在的原因。

S3存储桶名称在所有亚马逊网络服务账户中也是唯一的和全局的。
