'Problem authenticating via the OpenSea JDK

I am trying to authenticate my wallet against OpenSea using the SDK, but fail doing so.

Here's my code snippet:

const walletSubprovider = new MnemonicWalletSubprovider({
    mnemonic: MNEMONIC,
    baseDerivationPath: `44'/60'/0'/0`,
  })

const rpcSubprovider = new RPCSubprovider(RPC_URL)
const providerEngine = new Web3ProviderEngine()
providerEngine.addProvider(walletSubprovider)
providerEngine.addProvider(rpcSubprovider)
providerEngine.start()

const seaport = new OpenSeaPort(
    providerEngine,
    {
        networkName: Network.Main,
        apiKey: API_KEY,
    },
    (arg) => console.log(arg)
  );

I am using those versions:

@0x/[email protected]

This is the stack trace:

Does anyone have an idea what the problem might be?
