标签: validationexception

我试图在名为的DynamoDB表中插入新记录Users.我从表中获取数据.但每当我尝试插入新记录时,我都会收到以下错误 -

AWSiOSSDKv2 [Verbose] AWSURLResponseSerialization.m line:86 | -[AWSJSONResponseSerializer responseObjectForResponse:originalRequest:currentRequest:data:error:] | Response body: [{"__type":"com.amazon.coral.validate#ValidationException","message":"Supplied AttributeValue is empty, must contain exactly one of the supported datatypes"}]

我的问题是导致此异常的原因以及我得到它的原因是什么？我确信我没有任何空变量(你可以在附件中看到)

有关该问题的信息:

这是我想要做的完整日志 -

我在 Amazon EC2 上运行了 ac# asp.net 应用程序，但是出现验证错误：

异常类型： HttpRequestValidationException

异常信息： A potentially dangerous Request.RawUrl value was detected from the client (="...h&content=<php>die(@md5(HelloT...").

日志显示请求 url 是：

http://blah.com/?a=fetch&content=<php>die(@md5(HelloThinkCMF))</php>

那个 PHP die 脚本来自哪里？这是某种安全漏洞吗，我不知道如何调试。

我有一张表并设置了一个 GSI 来进行查询。我为其设置条件的属性是类型号。我为比较设置属性值，如下所示：AttributeValue value = new AttributeValue(); value.setN(String.valueOf(3));

我成功地进行了一个将比较运算符设置为 EQ 的查询。给出了正确的结果，但其他选项（ NE | LE | LT | GE | GT | 等）都不起作用。他们都抛出一个 ValidationException - 不支持查询关键条件（服务：AmazonDynamoDB；状态代码：400；...

我究竟做错了什么？

非常感激

我正在尝试更新 DynamoDB 表中的项目。我编写的代码正在更新该项目，但是当我添加标题为“源/目标”的列时，它给出了“ValidationException”异常。

用于更新的代码 -

dynamodb = boto3.resource('dynamodb')
table = dynamodb.Table("test")
response = table.update_item(
        Key={
        'id': "test_id            
        },
        UpdateExpression="set source/target= :st, user_name= :usr",
        ExpressionAttributeValues={
            ':st' : event['source/target'],
            ':usr' : event['user_name']
                },
        ReturnValues="UPDATED_NEW"
    )

我得到的错误是 -

调用UpdateItem操作时发生错误（ValidationException）：Invalid UpdateExpression：语法错误；标记：\"/\"，附近：\"源/目标\""

怎么解决这个问题呢？
