Cannot switch to certain networks with email wallets

[katlegoN]

Good day

I have currently enabled the email wallet feature on our web3modal configuration, we are developing on the core blockchain however it seems the email wallets cannot switch to certain networks like the core mainnet and testnet in our case, we tested on ethereum and everything seems to be working fine however we are developing on the core blockchain which seems to be an invalid network according to the error consoled on the browser logs from the web3modal, below is the code configuration

const mainnet = {
      chainId: 1116,
      name: "Core",
      currency: "CORE",
      explorerUrl: "https://scan.coredao.org",
      rpcUrl: "https://rpc.coredao.org",
    };

 const metadata = {
      name: "MyApp",
      description: "web3 app",
      url: "https://test.com", // url must match your domain & subdomain
      icons: [
        "https://test/assets/images/test.png",
      ],
    };

const ethersConfig = defaultConfig({
      metadata,
      enableEmail: true,

      enableEIP6963: true, // true by default
      enableInjected: true, // true by default
      enableCoinbase: true, // true by default
      rpcUrl: "https://rpc.coredao.org", // used for the Coinbase SDK
      defaultChainId: 1116, // used for the Coinbase SDK
    });

const modal = createWeb3Modal({
      ethersConfig,
      chains: [mainnet],
      projectId,
      enableAnalytics: true, // Optional - defaults to your Cloud configuration
      enableOnramp: true, // Optional - false as default
    });

here is the error on the console

{
    "type": "@w3m-app/SWITCH_NETWORK",
    "payload": {
        "chainId": 1116
    }
}
{
    "type": "@w3m-frame/SWITCH_NETWORK_ERROR",
    "payload": {
        "message": "Cannot read properties of undefined (reading 'chainId')"
    }
}
