amazon-web-services - Cloudformation 失败并显示 'failed validation constraint for keyword [pattern]'

Question

我正在尝试使用 AWS CloudFormation 创建工作流对象。此工作流程将与 AWS File Transfer 系列结合使用，以便文件在上传时复制到 S3。

AWSTemplateFormatVersion: "2010-09-09"

Resources:
  SftpToS3Workflow:
    Type: AWS::Transfer::Workflow
    Properties: 
      Description: 'Workflow used by AWS File Transfer Family. Copies the files to S3'
      Steps: 
        - Type: COPY
          CopyStepDetails:
            Name: copt-to-s3-wf-step
            DestinationFileLocation:
              S3FileLocation:
                Bucket: !ImportValue GenesysS3BucketName
                Key: "genesys/"
            OverwriteExisting: 'TRUE'
        
Outputs:
    SftpToS3WorkflowId:
      Description: 'Id of the Workflow'
      Value: !GetAtt SftpToS3Workflow.WorkflowId
      Export:
        Name: SftpToS3WorkflowId

不幸的是，该脚本失败并出现以下错误。该错误没有说明哪个属性未通过验证。有人可以帮忙吗？我在 GitHub 上找不到哪怕一个示例。

Properties validation failed for resource SftpToS3Workflow with message: #/Description: failed validation constraint for keyword [pattern]

我使用此 CloudFormation 架构来编写代码:

Description只能是

^[\w- ]*$

所以应该是:

Description: 'Workflow used by AWS File Transfer Family - Copies the files to S3'
