您必须添加 LocalSecondaryIndexes :

AWSTemplateFormatVersion: "2010-09-09"
Parameters:
  Env:
    Type: String
  CommitHash:
    Type: String

Resources:
  RecipeRecommendationDynamoDBTable:
    Type: AWS::DynamoDB::Table

      AttributeDefinitions:
        - AttributeName: "id"
          AttributeType: "S"
        - AttributeName: "topic"
          AttributeType: "S"
        - AttributeName: "position"
          AttributeType: "S"          
      KeySchema:

          KeyType: "RANGE"
      TimeToLiveSpecification:

        Enabled: true
      LocalSecondaryIndexes:

          KeySchema: 
            - AttributeName: "id"
              KeyType: "HASH"
            - AttributeName: "position"
              KeyType: "RANGE"           
          Projection:
