I have created a lambda java project to get items from dynamoDB.But I am getting error while accessing.
Code that I wrote:
dbClient = AmazonDynamoDBClientBuilder.standard().withRegion(Regions.US_EAST_1).build();
DynamoDB dynamoDB = new DynamoDB(dbClient);
Table table = dynamoDB.getTable("TokenSystem");
Item item = table.getItem("TokenId", 123456);
return item.toJSON();
Error getting in lambda console:
com.amazonaws.services.dynamodbv2.model.AmazonDynamoDBException: The provided key element does not match the schema (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: ValidationException; Request ID: 9OJVLPJHV011KLGKI20Q8QN2FNVV4KQNSO5AEMVJF66Q9ASUAAJG)
