我试图使用 DynamoDB JavaScript shell 创建一个简单的表，但我遇到了这个异常：

{
  "message": "The number of attributes in key schema must match the number of attributes defined in attribute definitions.",
  "code": "ValidationException",
  "time": "2015-06-16T10:24:23.319Z",
  "statusCode": 400,
  "retryable": false
}

下面是我试图创建的表：

var params = {
  TableName: 'table_name',
  KeySchema: [
    {
      AttributeName: 'hash_key_attribute_name',
      KeyType: 'HASH'
    }
  ],
  AttributeDefinitions: [
    {
      AttributeName: 'hash_key_attribute_name',
      AttributeType: 'S'
    },
    {
      AttributeName: 'attribute_name_1',
      AttributeType: 'S'
    }
  ],
  ProvisionedThroughput: {
    ReadCapacityUnits: 1,
    WriteCapacityUnits: 1
  }
};
dynamodb.createTable(params, function(err, data) {
  if (err) print(err);
  else print(data);
});

但是，如果我将第二个属性添加到KeySchema，它工作正常。在工作台下方：

var params = {
  TableName: 'table_name',
  KeySchema: [
    {
      AttributeName: 'hash_key_attribute_name',
      KeyType: 'HASH'
    },
    {
      AttributeName: 'attribute_name_1',
      KeyType: 'RANGE'
    }
  ],
  AttributeDefinitions: [
    {
      AttributeName: 'hash_key_attribute_name',
      AttributeType: 'S'
    },
    {
      AttributeName: 'attribute_name_1',
      AttributeType: 'S'
    }
  ],
  ProvisionedThroughput: {
    ReadCapacityUnits: 1,
    WriteCapacityUnits: 1
  }
};
dynamodb.createTable(params, function(err, data) {
  if (err) print(err);
  else print(data);
});

我不想将范围添加到键模式。知道如何解决吗？
