Ping Pong handling when override function in DefaultSocketSessionInterceptor

[dave-chow]

Hi there,

is there any sample code to talk about how to override OnPongAsync() in DefaultSocketSessionInterceptor? I tried the following, but failed to inject the payload the frontend.

public class CustomPayloadMessage : JsonOperationMessage
{
	public CustomPayloadMessage(JsonElement? payload = null)
		: base("pong", payload)
	{
	}
}

public override ValueTask OnPongAsync(ISocketSession session, IOperationMessagePayload pongMessage, CancellationToken cancellationToken = default(CancellationToken))
	{
		string jsonString = @"{
			""Date"": ""2019-08-01T00:00:00-07:00"",
			""TemperatureCelsius"": 25,
			""Summary"": ""Hot""
		}";

		var document = JsonDocument.Parse(jsonString);
		var customPayload = new CustomPayloadMessage(document.RootElement);
		return base.OnPongAsync(session, customPayload, cancellationToken);
	}

In frontend, using graphql-ws, and listen to pong event, but get false in received, and null in paylaod

wsClient.on('pong', (received: any, payload: any) => {
	console.log("pong");
	console.log(received);
	console.log(payload);
});

Thanks!
