Hey guys, i'm trying to implement the custom auth using JWT token. I've successfully deployed the verified in the dashboard but i get some weird errors. Here is a snippet of my code. Any clues on whats going wrong ?

`

http://localhost:8080",  
verifierIdField: "sub",  
response\_type: "token",  
scope:"",  
}  
});"\>

```
const web3authCore = new Web3AuthCore({
chainConfig: {
chainNamespace: CHAIN_NAMESPACES.EIP155,
chainId: “0x38”,
rpcTarget: “https://bsc-dataseed1.binance.org”,
blockExplorer: “https://bscscan.com/”,
ticker: “BNB”,
tickerName: “Binance Smart Chain”,
},
clientId: “”
});
const adapter = new OpenloginAdapter({ adapterSettings: {
network: “testnet”,
clientId: “”,
uxMode: “popup”,
loginConfig: {
jwt: {
name: “any name”,
verifier: “wam-testnet”,
typeOfLogin: “jwt”,
clientId: “”,
},
},
}});
web3authCore.configureAdapter(adapter);
await web3authCore.init();

```
