Hi, I just want to get the latest block number . I followed the docs, but getting the error

const provider = new ethers.providers.AlchemyProvider(
                                      ^

TypeError: Cannot read properties of undefined (reading 'AlchemyProvider')
    at Object.<anonymous> (D:\BlockChain\Ether JS\readBlockchain.js:5:39)

    at node:internal/main/run_main_module:17:47

Here is my code :

const { ethers } = require("ethers");

const network = "mainnet";
const demo = api_key;
const provider = new ethers.providers.AlchemyProvider(
  network,
 demo
);

const querryBlockchain = async () => {
  const blockNumber = await provider.getBlockNumber();
  console.log(blockNumber);
};

querryBlockchain();
