dynamoDB查询与HashKeyValue和RangeKeyCondition不工作的JavaScript

Question

我执行使用JavaScript以下dynamoDB查询：

dynamoDB.query({ 
     "TableName" :"table_name", 
     "IndexName": "Approval-Date-index", 
     "HashKeyValue": {"Approval": {"AttributeValueList": [{"S": 'Approved'}],"ComparisonOperator": "EQ"}}, 
     "RangeKeyCondition" : {"Date" : {"AttributeValueList": [{"S": "0"}]}}, 
     // "ScanIndexForward" : true, 
     "AttributesToGet":["Id","Url","userName","userPicture","Title","Date","Type","Description"] 
    }, 
    function(error, result) 
    { 
     console.log(result); 
     console.log(error); 
    }); 

我收到以下错误：

ValidationException:1 validation error detected: Value null at 'rangeKeyCondition.comparisonOperator' failed to satisfy constraint: Member must not be null

Answer 1

对我来说，它给了我相同的错误 “ValidationException：1检测到验证错误：'rangeKeyCondition.comparisonOperator'处的值null未能满足约束：成员不能为空” 我做的是更新Dynamodb SDK，我解决了问题
