DynamoDB result is not structured the way I want - amazon-dynamodb

Question

I am doing a simple command to list all the items in my table. However, the data I am getting back is not structured the way I want. I want a simple JSON structure but DynamoDB is turning the results into nested objects.
DynamoDB gives me below response:
// What I am currently getting
[
{
id: { S: '8' },
lastName: { S: 'Perry' },
firstName: { S: 'Matthew' }
},
{
id: { S: '3' },
firstName: { S: 'Joan' },
lastName: { S: 'Peter' }
}
]
But I want this:
// What I want
[
{
id: 8
lastName: 'Perry' ,
firstName: 'Matthew'
},
{
id: 3,
firstName: 'Joan' ,
lastName: 'Peter'
}
]
How can I achieve the later result set. Below is my code:
const { ExecuteStatementCommand } = require('#aws-sdk/client-dynamodb')
const { ddbDocClient, memberTableName } = require('./client.js')
const selectAll = async () => {
const params = {
Statement: `SELECT * FROM ${memberTableName}`,
Parameters: [{ S: '3' }]
}
console.log(params)
return await ddbDocClient.send(new ExecuteStatementCommand(params));
}
selectAll()
.then(d => console.log(d.Items))
ddbDocClient was created like this:
const ddbDocClient = DynamoDBDocumentClient.from(ddbClient);

Answer 1

The command import is incorrect. To send and receive native JS types, import the ExecuteStatementCommand command from the #aws-sdk/lib-dynamodb "document client" package.
const { ExecuteStatementCommand } = require('#aws-sdk/lib-dynamodb');
You are importing the command from the "regular client" package #aws-sdk/client-dynamodb, i.e. the one that accepts and returns DynamoDB JSON.
Note: The Parameters: [{ S: '3' }] line is also wrong, but it's currently not causing trouble because your statement is scanning for all records. If you were to include a WHERE id=? phrase in the statement, make sure to change the parameters to Parameters: ['3']. You must pass JS types to the "document client" commands.

You need use simple lib https://www.npmjs.com/package/#aws-sdk/util-dynamodb
then use like this:
const { DynamoDB } = require("#aws-sdk/client-dynamodb");
const { marshall, unmarshall } = require("#aws-sdk/util-dynamodb");
const client = new DynamoDB(clientParams);
const params = {
TableName: "Table",
Key: marshall({
HashKey: "hashKey",
}),
};
const { Item } = await client.getItem(params);
unmarshall(Item);
