I am struggiling with this error - SEVERE: 2022-08-16 16:01:01.915620: Failed to complete negotiation with the server: TimeoutException after 0:00:02.000000: Future not completed
If there any chance to prevent it? I get a big pile of data and I don't want my websocket connection to fail and I need to wait until it is all done. As I understand it is not a backend issue (or, may be, I wrong, because I have searched a lot and any solutions dosen't work for me).
My code is like that:
Future<List> fetchAllBugStuff() async {
Logger.root.level = Level.ALL;
Logger.root.onRecord.listen((LogRecord rec) {
print('${rec.level.name}: ${rec.time}: ${rec.message}');
});
final transportProtLogger = Logger("SignalR - transport");
Logger? logger;
final httpConnectionOptions = HttpConnectionOptions(
accessTokenFactory: () => SharedPreferenceService().loginWithToken(),
headers: defaultHeaders,
logger: transportProtLogger,
logMessageContent: true,
);
final hubConnection = HubConnectionBuilder()
.withUrl(
'http://10.10/home',
options: httpConnectionOptions,
)
.build();
await hubConnection.start();
List fixation = [];
if (hubConnection.state == HubConnectionState.Connected) {
await hubConnection
.invoke('GetAllBigStuff')
.then((value) => fixation = value as List);
}
hubConnection.keepAliveIntervalInMilliseconds = 10 * 60 * 60 * 1000;
hubConnection.onclose(({error}) {
Logger.root.level = Level.SHOUT;
Logger.root.onRecord.listen((LogRecord rec) {
print('${rec.level.name}: ${rec.error}: ${rec.message}');
});
logger?.finer(error);
});
// print(fixation);
return fixation;
}
