DynamoDB - with AWS SDK

Identify the error in this DynamoDB Document Client code snippet:

const params = { TableName: "Products", Item: { id: 101, name: "Pen" } };
const command = new GetCommand(params);
const result = await docClient.send(command);
console.log(result);

AUsing GetCommand with an Item parameter instead of Key

BMissing await keyword before docClient.send

CTableName should be lowercase

DItem should be a string, not an object

Step-by-Step Solution

Solution:

Step 1: Check command and parameters
GetCommand requires a Key parameter to identify the item, not an Item parameter.
Step 2: Validate other options
Await is present, TableName is case-sensitive but correct, and Item must be an object for PutCommand, not GetCommand.
Final Answer:
Using GetCommand with an Item parameter instead of Key -> Option A
Quick Check:
GetCommand needs Key, not Item = D [OK]

Quick Trick: GetCommand uses Key, PutCommand uses Item [OK]

Common Mistakes:

MISTAKES

Confusing Item and Key parameters
Ignoring case sensitivity of TableName
Forgetting await keyword
