Hi Mateusz.

Does your own custom service use UmbracoContext that it not called by UmbracoContextFactory by any chance?

You need to be sure that all UmbracoContext is called by the Factory like.

using (var ctx = UmbracoContextFactory.EnsureUmbracoContext())
{
    // ctx.UmbracoContext.Content.GetById(1000);
}

Hi Bo,

indeed, my custom service uses UmbracoContextFactory by injection but when it comes to use it, in every single place following pattern is applied:

using (var cref = _umbracoContext.EnsureUmbracoContext())
{
    // do stuff...
}

Maybe I need to clarify, the mentioned error appears during Task instance initialization, which means the execution does not even reach the construstor.

Ok so here is a task class implementation:

public interface IDummyTask
{
    void Execute(PerformContext context, CancellationToken token);
    void DoJob();
}

public class DummyTask : IDummyTask
{
    private readonly string _taskName;
    private readonly IUmbracoContextFactory _umbracoContextFactory;
    private readonly IImportTourDataService _tourImporter;

    public DummyTask(IDummyService dummyService, IImportTourDataService importer, IUmbracoContextFactory umbracoContextFactory)
    {
        _taskName = dummyService.GetTaskName();
        _umbracoContextFactory = umbracoContextFactory;
        _tourImporter = importer;
    }

    public void DoJob()
    {
        Thread.Sleep(5000);
    }

    public void Execute(PerformContext context, CancellationToken token)
    {
        RecurringJob.AddOrUpdate<IDummyTask>(_taskName, x => x.DoJob(), "* * * * *");
    }
}

public interface IDummyService
{
    string GetTaskName();
}

public class DummyService : IDummyService
{
    public string TaskName => "DummyTask";

    public string GetTaskName()
    {
        return TaskName;
    }
}

When I remove IImportTourDataService from the constructor - all works fine. So it seems to be an issue.

So here is the constructor's header from the IImportTourDataService implementation:

public ImportTourDataService(IUmbracoContextFactory umbracoContext,
                                 IExamineManager examineManager, 
                                 IHubContext<TourImportHub> hubContext, 
                                 IContentService contentService,
                                 ITourImporter<ExtendedSeasonNodeImporter> tourImporter,
                                 ITourImporter<DateRateCoordinatedDbImporter> datesAndRatesImporter,
                                 ISiteManager siteManager, 
                                 ILogger logger, 
                                 IBrandRegionsService brandRegionsService,
                                 IScopeProvider scopeProvider,
                                 IFacebookFeedService facebookFeedService, 
                                 IIndexCreatorService indexCreator)

Forgot to mention: both my services: DummyTask and ImportTourDataService are registered in IoC as transient.

Another observation: when I inject IDummyTask (with all 3 services injected via DummyTask constructor) into some controller for example it also seems to work.

It looks like the issue with how Hangfire resolves dependencies (?)

Did you find a solution to this? I'm having the same problem.

is working on a reply...
