I am getting the following error when Connecting to Bifrost wss://bifrost-polkadot.api.onfinality.io/public-ws rpc:

try
{
    var endpoint = PlutoWallet.Constants.Endpoints.GetEndpointDictionary["bifrost"];

    //string bestWebSecket = await WebSocketModel.GetFastestWebSocketAsync(endpoint.URLs);

    client = new SubstrateClientExt(
        endpoint, // This is my modification, can be ignored
        new Uri("wss://bifrost-polkadot.api.onfinality.io/public-ws"),
        Substrate.NetApi.Model.Extrinsics.ChargeTransactionPayment.Default());

    await client.ConnectAsync();
}
catch (Exception ex)
{
    // Prints the error written at the top
    Console.WriteLine(ex);
}

{"jsonrpc":"2.0","result":{"ss58Format":6,"tokenDecimals":[12],"tokenSymbol":["BNC"]},"id":1}

{"jsonrpc": "2.0", "result": {"ss58Format": 1337,"tokenDecimals": 12,"tokenSymbol": "BAJU"},"id": 1}

Might need to move it to a object, instead of a typed return value.
