AWS - DynamoDB

You wrote this code to get an item but it throws an error:

const params = {
  TableName: 'Products',
  Key: { productId: 101 }
};
const data = await dynamoDBClient.getItem(params);
console.log(data.Item);

What is the likely cause of the error?

AThe key attribute value must be a string, not a number

BThe method should be <code>get</code> instead of <code>getItem</code>

CMissing <code>KeyConditionExpression</code> in parameters

DTableName is incorrect

Step-by-Step Solution

Solution:

Step 1: Check the key attribute type
DynamoDB keys must be typed as attribute values, usually strings or objects with type wrappers.
Step 2: Identify the error cause
Passing a plain number (101) without type wrapper causes a validation error.
Final Answer:
The key attribute value must be a string, not a number -> Option A
Quick Check:
Key values need correct type format [OK]

Quick Trick: Key values must be strings or typed attributes [OK]
