AmazonServiceException：Supplied AttributeValue爲空，必須包含其中一個受支持的數據類型

Question

我試圖從dynamodb控制檯界面導入數據，但無法獲得成功。

數據是

{"_id":{"s":"d9922db0-83ac-11e6-9263-cd3ebf92dec3"},"applicationId":{"S":"2"},"applicationName":{"S":"Paperclip"},"ip":{"S":"127.0.0.1"},"objectInfo":{"S":"elearning_2699"},"referalUrl":{"S":"backported data"},"url":{"S":""},"userAgent":{"S":""},"userEmail":{"S":"karthick.shivanna@test.com"},"userId":{"S":"508521"},"userName":{"S":"Karthik"},"created":{"S":"1486983137000"},"verb":{"S":"submitproject"},"dataVals":{"S":"{\"projectid\":5,\"name\":\"Test 1\",\"domain\":\"apparel\",\"submittype\":[\"Writeup\",\"Screenshots\"],\"passcriteria\":\"Percentage\",\"taemail\":\"bhargava.gade@test.com\",\"attemptNo\":1,\"submitDate\":1467784988}"},"eventTime":{"S":"1467784988000"}} 

我得到以下錯誤

難道我做錯了什麼？

Answer 1

錯誤：了java.lang.RuntimeException：com.amazonaws.AmazonServiceException：提供的AttributeValue是空的，必須包含完全支持的數據類型之一（服務：AmazonDynamoDBv2;狀態代碼：400;錯誤代碼：ValidationException這是錯誤你得到。

下面是可能的原因

1. DynamoDB不支持空值，所以你應該刪除這些 字段（@notionquest同意）
2. 字段的值應該具有適當的數據類型，如表所示

Answer 2

我們必須在這裏一步一步地經歷。發生上述錯誤是因爲某些屬性的值爲空。 DynamoDB不支持屬性的空值。

例如：URL，等的userAgent

請取出空的屬性，然後再試一次。我可以保證上述問題將得到解決。但是，其他情況也可能是錯誤的。

Answer 3

在我的情況下，我得到了同樣的問題，因爲從 映射模板無效的參數發送。

#set($inputRoot = $input.path('$')) 
{ 
    "userId": "$input.params('userId')", 
    "userEmail": "$input.params('userEmail')", 
    "userName": "$input.params('userName')", 
    "userPassword": "$input.params('userPassword')" 
} 

在這裏我發送了額外的參數userId，這就是爲什麼發生錯誤。

---

而對於空白值，添加項目時，主鍵屬性是唯一必需的屬性。屬性值不能爲空。字符串和二進制類型屬性的長度必須大於零。設置類型屬性不能爲空。具有空值的請求將被拒絕，並出現ValidationException異常。 請檢查這個文件。

http://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_PutItem.html

我希望這會幫助你。

Answer 4

我在運行aws中的還原管道時遇到同樣的問題。經過一段時間後，我發現問題。 AMI版本的恢復與導出的版本不同。

我有其他管道工作正常。我仍然不知道爲什麼在一起案件中沒有。基本上，我檢查了AMI版本，它們是3.8.0的出口版本和3.9.0的恢復版本。我將還原更改爲3.8.0，它可以正常工作。

在這裏您會找到更好的explanation。

我的兩分錢。
