I am trying to use OpenSea API with the JS SDK. I am getting two types of errors. One is a deprecated warning. Another is a 404 error. This is the error I am getting no matter what request is performed,

DEPRECATED: Please use providerUtils.standardizeOrThrow() instead

Here is my code following the documentation,

const Web3 = require("web3");
const { OpenSeaPort, Network } = require("opensea-js");

const HDWalletProvider = require("@truffle/hdwallet-provider");

const privateKeys = [
    "private key",
];

const provider = new HDWalletProvider(
    privateKeys,
    "https://polygon-mainnet.g.alchemy.com/v2/aclchemy - key",
    0,
    2
);

const seaport = new OpenSeaPort(provider, {
    networkName: Network.Main,
    apiKey: "api key",
});

const getAsset = async () => {
    const asset = {
        tokenAddress: "0x0ee7d6519a475a35e5c65dd0193dd1b9800e4db0", // CryptoKitties
        tokenId: "129", // Token ID
    };

    const listing = await seaport.api.getAsset(asset);

    console.log(listing);
};

getAsset();

The RPC API key is from Alchemy.
