无服务器框架 Dynamo DB 表资源定义（带排序键）

目前，我的 serverless.yml 中有一些这样的代码。

resources:
  Resources:
    uploadBucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: ${self:service}-${self:custom.stage}-uploads
    visitsTable:
      Type: AWS::DynamoDB::Table
      Properties:
        TableName: ${self:custom.visitsTable}
        AttributeDefinitions:
          - AttributeName: userId
            AttributeType: S
          - AttributeName: visitId
            AttributeType: S
          - AttributeName: comments
            AttributeType: S
          - AttributeName: attachments
            AttributeType: S
          - AttributeName: ph
            AttributeType: N
          - AttributeName: ch
            AttributeType: N
        KeySchema:
          - AttributeName: userId
            KeyType: HASH
          - AttributeName: visitId
            KeyType: HASH
        ProvisionedThroughput:
            ReadCapacityUnits: 5
            WriteCapacityUnits: 5

我的目标是创建一个包含主键 userId、排序键 VisitId 并包含评论、附件、ph 和 ch 字段的表。当我尝试sls deploy我收到以下错误。

无服务器错误 --------------------------------------

发生错误：visitsTable - 属性AttributeDefinitions 与表和二级索引的KeySchema 不一致。

我在这里做错了什么？

编辑：我尝试过的另一次尝试

resources:
  Resources:
    uploadBucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: ${self:service}-${self:custom.stage}-uploads
    visitsTable:
      Type: AWS::DynamoDB::Table
      Properties:
        TableName: ${self:custom.visitsTable}
        AttributeDefinitions:
          - AttributeName: userId
            AttributeType: S
          - AttributeName: visitId
            AttributeType: S
        KeySchema:
          - AttributeName: userId
            KeyType: HASH
          - AttributeName: visitId
            KeyType: RANGE
        ProvisionedThroughput:
            ReadCapacityUnits: 5
            WriteCapacityUnits: 5

AWS DynamoDb 是一个 NO-SQL 类型数据库，无需在表创建过程中定义所有键。 AWS 文档还清楚地表明，在属性定义中，您必须指定密钥架构和索引。

描述表和索引的键架构的属性数组。

请按如下方式编辑您的代码

resources:
  Resources:
    uploadBucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: ${self:service}-${self:custom.stage}-uploads
    visitsTable:
      Type: AWS::DynamoDB::Table
      Properties:
        TableName: ${self:custom.visitsTable}
        AttributeDefinitions:
          - AttributeName: userId
            AttributeType: S
          - AttributeName: visitId
            AttributeType: S
        KeySchema:
          - AttributeName: userId
            KeyType: HASH
          - AttributeName: visitId
            KeyType: RANGE
        ProvisionedThroughput:
            ReadCapacityUnits: 5
            WriteCapacityUnits: 5
