Additional headers only sent on first request with negotiate, but not sending with message

[MohammadElKhatib]

I am using signalr_netcore: ^1.4.0 and flutter version 3.27.0 but as you can see i am still facing issue with the headers where i send an api key that is been sent during negotiate but not sent after that, below code and log

`
Future connectToHub() async {
Logger.root.level = Level.ALL;
_logMessagesSub = Logger.root.onRecord.listen(_handleLogMessage);
_logger = Logger("ChatPageViewModel");

final defaultHeaders = MessageHeaders();
defaultHeaders.setHeaderValue("X-Api-Key", apiKey);

var httpConnectionOptions = HttpConnectionOptions(
    accessTokenFactory: () => Future.value(getToken()),
    headers: defaultHeaders,
    logger: _logger,
    logMessageContent: true);

hubConnection = HubConnectionBuilder()
    .withUrl(chatHubUrl, options: httpConnectionOptions)
    .withAutomaticReconnect(retryDelays: [2000, 5000, 10000])
    .build();

hubConnection.onclose(({Exception? error}) {
  connectionIsOpen = false;
});

hubConnection.onreconnecting(({error}) {
  CustomLogger.devLog("onreconnecting called");
  connectionIsOpen = false;
});

hubConnection.onreconnected(({connectionId}) {
  CustomLogger.devLog("onreconnected called");
  connectionIsOpen = true;
});

hubConnection.on("ReceiveMessage", _handleIncomingChatMessage);
hubConnection.on("UserIsTyping", _handleUserIsTyping);
hubConnection.on("UserStatusUpdated", _handleUsersStatusUpdated);
await startConnection();

}

No not really i modified the backend to ignore the api key for signalr connections only until it is fixed.
