Now I suspect it is because that Request Time out settings of .Host project, I tested locally, since change the settings, has no impact. Locally testing can always process large data, but for deployed code, the application throw exception at certain amount of data. I also noticed that the request is triggered again when first request failed, is it because Abp gateway's auto feature?

Hi @maiiming,

I sent you exception call stack via email.

The code disable entrance API's unit of work, because the whole process involves other resources access which might take long time, wrap data access code by unit of work at the steps need to access database.

Thanks, Domina

When Angular calls API which trigger a long operational call, the entrance App Service method has [UnitOfWork(IsDisabled = true)]. This App Service call several other App Services. Within these App Services there are several places need to access/update MongdoDb, for those data access, use code below:

using (var uow = _unitOfWorkManager.Begin(requiresNew: true, isTransactional: true))
 {
    ...
    await uow.CompleteAsync();         
}

But still MongoDb throw exception. For these App Services Methods called by entrance App Service, do I need to add [UnitOfWork(IsDisabled = true)] annotation too? Thanks,

Do you have a sample code for SignalR send message to Angular app. Angular get 502 for negociate.

In Micro Service Application module: typeof(AbpAutoMapperModule),

Configure<AbpSignalROptions>(options =>
{
    options.Hubs.AddOrUpdate(
        typeof(NotificationHub), //Hub type
        config => //Additional configuration
        {
            config.ConfigureActions.Add(hubOptions =>
            {
                //Additional options
                hubOptions.LongPolling.PollTimeout = TimeSpan.FromSeconds(30);
            });
        }
    );
});

In Gateway module:

app.UseWebSockets();
        app.UseOcelot().Wait();
        app.UseRouting()

{
      "ServiceKey": "SignalR Service",
      "DownstreamPathTemplate": "/signalr-hubs/{evertything}",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "localhost",
          "Port": 45186
        }
      ],
      "UpstreamHttpMethod": [ "POST" ],
      "UpstreamPathTemplate": "/signalr-hubs/{evertything}",
      "ReRouteIsCaseSensitive": false
    },
    {
      "ServiceKey": "SignalR Service",
      "DownstreamPathTemplate": "/signalr-hubs/{everything}",
      "ReRouteIsCaseSensitive": false,
      "DownstreamScheme": "ws",
      "DownstreamHostAndPorts": [
        {
          "Host": "localhost",
          "Port": 45186
        }
      ],
      "UpstreamPathTemplate": "/signalr-hubs/{anyHub}",
      "UpstreamHttpMethod": [ "GET", "POST", "PUT", "DELETE", "OPTIONS" ]
    },

Figured out the reason. It is because of wrong grand type setting (should use grand type "code", but the angular app users resource owner.

Hi Ming,

With Dev Tools, we check network traffic and cookies, current tenant's Id is null. That is why this ticket is raised. But Developer local debugging, everything seems fine.

Thanks, Domina

The abp sample code that get access token works (https://github.com/bartvanhoey/), I tested that both client credential and resource owner grant type work.

It might because the app already use Rabbit MQ as service bus. Ignore this ticket.

After deployed the application (Micro-Service template) to Azure Kubernates, Choose an tennant from login screen, however the tennantId is null while inspect the network traffic from browser. Local works fine.

Do you have any clue about the reason?
