Cloudformation 失败 'failed validation constraint for keyword [pattern]'

Question

我正在尝试使用 AWS CloudFormation 创建工作流对象。此工作流将与 AWS 文件传输系列一起使用，以便文件在上传时被复制到 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，此脚本因以下错误而失败。该错误没有说明属性验证失败的原因。有人可以帮忙吗？我在 GitHub.

上连一个例子都找不到

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

我使用此 CloudFormation 架构编写代码：

Description只能是

^[\w- ]*$

所以应该是：

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

Cloudformation 失败 'failed validation constraint for keyword [pattern]'
