Subscription not getting data even after client succesfully connects

Hello,

I'm using Spring Boot Netflix DGS as my graph server, trying to connect with C# as a client for a subscription

While looking through the other issues posted on here ive pieced this together, this is a basic new c# console app, so im just keeping while true to stop the app from exiting after subscribing to the subscription. I can see on my java server the log message client connected, but I don't get any data back from the subscription. I can confirm the subscription works with other tools like apollo playground. I'm not geting any error, just not geting any data back.

Java server code

` @DgsSubscription
public Publisher gameStates() {
log.info("Client connected");
return gameService.getGameStatePublisher();
}`

### C# Code

` var gameStateSubscriptionRequest = new GraphQLRequest
{
Query = @"
subscription{
gameStates{
id
}
}"
};

// Create JsonSerializer
var serializerSettings = new JsonSerializerSettings
{
ContractResolver = new CamelCasePropertyNamesContractResolver { IgnoreIsSpecifiedMembers = true },
MissingMemberHandling = MissingMemberHandling.Ignore
};
serializerSettings.Converters.Add(new ConstantCaseEnumWorkaroundConverter());

// See https://github.com/graphql-dotnet/graphql-client/issues/311
var jsonSerializer = new NewtonsoftJsonSerializer(serializerSettings);

// Establish Client
var _subscriptionClient = new GraphQLHttpClient(o =>
{
o.WebSocketEndPoint = new Uri("ws://localhost:8080/subscriptions");
o.UseWebSocketForQueriesAndMutations = false;
},
jsonSerializer);

var subscriptionStream = _subscriptionClient.CreateSubscriptionStream(gameStateSubscriptionRequest);

var subscription = subscriptionStream.Subscribe(response =>
{
Console.WriteLine("Data is");
Console.WriteLine(response.Data);
});

while (true)
{
}`
