Getting error while running program in node js related to solana web3

Question

I am trying to starting code to name my solana token i was following but he was sucessful but i am not. I am using ubuntu and I am coding in vscode and running the program like ts-node main.ts. How to name your solana token Here is my code

import * as mpl from "@metaplex-foundation/mpl-token-metadata"
import * as web3 from "@solana/web3.js"

export function loadWalletKey(keypairFile:string): web3.Keypair
{
    const fs = require("fs");
    const loaded = web3.Keypair.fromSecretKey(
        new Uint8Array(JSON.parse(fs.readFileSync(keypairFile).toString())),
    );
    return loaded;
}


async function main(){
console.log("starting");
const myKeypair = loadWalletKey("BnAkGcoFJ9J7h3ZK8k3ZxbYQfa5RfEKmhz6UfxdwLR5d.json");
console.log(myKeypair.publicKey);
const accounts = {
    metadata:web3.PublicKey,
    mint:web3.PublicKey,
    mintAuthority:web3.PublicKey,
    payer:web3.PublicKey,
    updateAuthority:web3.PublicKey,
}
//mpl.createCreateMetadataAccountInstruction(accounts,args);
}

main();

And here is the error i am getting.

/home/cube/typescripts/node_modules/@solana/web3.js/lib/index.cjs.js:644
        keyMeta.isSigner ||= accountMeta.isSigner;
                           ^

I am expecting it to work the same without errors and print the public key as of video as of 12:00 to 12:25 i think in video.

Be sure to update to at least Node version 16. The newer web3.js library uses the ||= syntax which is unsupported for versions before 16.
