Estoy tratando de autenticar mi billetera contra OpenSea usando el SDK, pero no lo hago.

Aquí está mi fragmento de código:

 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) );

Estoy usando esas versiones:

 @0x/subproviders@6.6.5 opensea-js@3.0.4

Este es el seguimiento de la pila:

¿Alguien tiene una idea de cuál podría ser el problema?
