如何在Architect Serverless Framework中使用索引进行查询？

resources:
  Resources:
    MyTable:
      Type: AWS::DynamoDB::Table
      Properties:
        TableName: my-table
        AttributeDefinitions:
          - AttributeName: id
            AttributeType: N
        KeySchema:
          - AttributeName: id
            KeyType: HASH
        ProvisionedThroughput:
          ReadCapacityUnits: 1
          WriteCapacityUnits: 1

functions:
  query:
    handler: handler.query
    events:
      - http:
          path: query
          method: get

const AWS = require('aws-sdk');
const dynamodb = new AWS.DynamoDB.DocumentClient();

module.exports.query = async (event, context) => {
  const params = {
    TableName: 'my-table',
    IndexName: 'index-name',
    KeyConditionExpression: 'partitionKey = :partitionKey',
    ExpressionAttributeValues: {
      ':partitionKey': 'value'
    }
  };

  try {
    const result = await dynamodb.query(params).promise();
    return {
      statusCode: 200,
      body: JSON.stringify(result.Items)
    };
  } catch (error) {
    return {
      statusCode: 500,
      body: error.message
    };
  }
};
