Method not found | rpcMethod: 'open_wallet'
So I need to code a payment system that supports monero and I'm having a little problem loading the wallet already generated on the monero GUI. As soon as I try to run the code to use `app.wallet` I get this error:
```
MoneroRpcError: Method not found

}

Node.js v18.16.0

*Hackers who have the password, you won't get far it's a stagenet wallet lol*
Here is my code: 
```js
const walletRpc = await moneroTs.connectToWalletRpc(`http://${config.wallet.host}:${config.wallet.port}`);
app.wallet = await walletRpc.openWallet({
    path: './wallet/PrefixOfPrivacy',
    password: config.wallet.password,
    networkType: moneroTs.MoneroNetworkType.STAGENET,
    seed: config.wallet.seed,
    restoreHeight: config.wallet.restore_height,
});
```
**IT IS IMPORTANT TO NOTE THAT CONFIG.WALLET IS GOOD! I have checked everything.**
config.json: 
```json
"wallet": {
    "host": "node3.monerodevs.org",
    "port": 38089
}
```
I use a public node in stagenet
**Thank you to anyone who can help me with this problem, which is a major obstacle to my project.**
