'getBlockWithTransactions' does not include 'size' in its response

Environment

• Node.js version: 22.11.0
• Alchemy SDK version: 3.4.8

The problem

getBlockWithTransactions does not include size in its response as mentioned in the docs. It is listed in the response object parameters, but does not appear in the example response.

How to reproduce:

import { Alchemy, Network } from 'alchemy-sdk';

const alchemy = new Alchemy({
  apiKey: ALCHEMY_API_KEY,
  network: Network.ETH_MAINNET,
});

console.log((await alchemy.core.getBlockWithTransactions(21179399)).size);
// undefined

The size is present in the JSON-RPC response of eth_getBlockByNumber. Here is the sandbox link for the same block.

Given that the core Alchemy method getBlockWithTransactions calls the Ethers.js provider method of the same name and this does not return the size, the docs should be updated and have the parameter removed from the response object.

For now, the alternative is to use the JSON-RPC call of eth_getBlockByNumber:

import { Alchemy, Utils, Network } from 'alchemy-sdk';

const alchemy = new Alchemy({
  apiKey: ALCHEMY_API_KEY,
  network: Network.ETH_MAINNET,
});

const ethersProvider = await alchemy.config.getProvider();
const block = await ethersProvider.send(
  'eth_getBlockByNumber',
  [
    Utils.hexValue(21179399),
    true
  ]
);

console.log(Number(block.size)); 
// 32548
