Hi Keerthi you need to pass a json with of type Dictionary<string, AttributeValue> in my case my dynamodb table has a key called searchid which is a string so I pass the following json:
{"searchid": {"S": "321"}}
you can get more information on the attributevalue here https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_Get.html
I dont aware that much of passing the Json,
But let me explain what i did.
I have created a local structure
and i am assigning the values
UserId is the Key which is a string which i have created in DynamoDb fo testing purpose
I am getting this error
I think i made some mistakes in JSON,
the following is the table and the elements
Hi Keerthi
The problem is with your structure it won't serialize into the json format that the dynamodb is expecting, I made an example on how you should create your structures
Thanks for the Guide,
Getting another error
I think i need to add attribute value, but what is that attribute value?
can you debug and share the Json that is serialized
I found the mistake ..
I rectified
I got the response
How can i make this as a output structure?
Will De serializing automatically create the structure or should we need to define?
If your DynamoDB has both a Primary Partition Key and a Primary Sort Key you MUST use BOTH keys in the GetItem something like:
For Example: If my Primary Key is ec2 and the sort key is eu-west-2:
"{""myprimarykey"": {""S"":""ec2""}, ""mysortkey"":{""S"": ""eu-west-2""}}"
