amazon-dynamodb - AmazonServiceException : Supplied AttributeValue is empty, 必须恰好包含一种受支持的数据类型

Question

我正在尝试从 dynamodb 控制台界面导入数据，但无法成功。

数据是

{"_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"}}

我得到以下错误

我做错了什么吗？

DynamoDB 不支持空值，因此您应该删除那些
字段(同意@notionquest)

字段的值应根据表具有正确的数据类型
