AWS - DynamoDB

You wrote this code to put an item but it fails with a validation error:

const params = { TableName: 'Orders', Item: { OrderId: '123', Amount: 50 } };
await client.put(params);

What is the likely cause?

AItem attributes must be wrapped with DynamoDB types like { S: '123' }

BTableName is incorrect

CPut operation requires a Key parameter

DAmount cannot be a number

Step-by-Step Solution

Solution:

Step 1: Check item attribute format
DynamoDB expects attribute values wrapped with type descriptors like { S: 'string' } or { N: 'number' }.
Step 2: Identify missing type wrappers
The code uses raw values without type wrappers, causing validation error.
Final Answer:
Item attributes must be wrapped with DynamoDB types like { S: '123' } -> Option A
Quick Check:
Put item values need type wrappers [OK]

Quick Trick: Wrap item values with DynamoDB types like { S: 'text' } [OK]
