NullExceptionError on v5.0.1 MVC Core Angular #4222

Hello,

We recently purchased a key to the boilerplate and once we downloaded and installed all of the files whenever we go to load the API up we encounter a NullExceptionError being passed into

var subscriptionExpiredTenants

I believe this is where the subscriptions information is passed in from the tenant information and as it's factory settings I'm not sure why it's occurring, for the meantime we can get around it by commenting out as shown below but this is not ideal. Any ideas guys?

protected override void DoWork()
        {
            var utcNow = Clock.Now.ToUniversalTime();
            var failedTenancyNames = new List<string>();
            /*
            var subscriptionExpiredTenants = _tenantRepository.GetAllList(
                tenant => tenant.SubscriptionEndDateUtc != null &&
                          tenant.SubscriptionEndDateUtc <= utcNow &&
                          tenant.IsActive &&
                          tenant.EditionId != null
            );

            foreach (var tenant in subscriptionExpiredTenants)
            {
                Debug.Assert(tenant.EditionId.HasValue);

                try
                {

                    var edition = _editionRepository.Get(tenant.EditionId.Value);

                    Debug.Assert(tenant.SubscriptionEndDateUtc != null, "tenant.SubscriptionEndDateUtc != null");

                    if (tenant.SubscriptionEndDateUtc.Value.AddDays(edition.WaitingDayAfterExpire ?? 0) >= utcNow)
                    {
                        //Tenant is in waiting days after expire TODO: It's better to filter such entities while querying from repository!
                        continue;
                    }

                    var endSubscriptionResult = AsyncHelper.RunSync(() => _tenantManager.EndSubscriptionAsync(tenant, edition, utcNow));

                    if (endSubscriptionResult == EndSubscriptionResult.TenantSetInActive)
                    {
                        _userEmailer.TryToSendSubscriptionExpireEmail(tenant.Id, utcNow);
                    }
                    else if (endSubscriptionResult == EndSubscriptionResult.AssignedToAnotherEdition)
                    {
                        AsyncHelper.RunSync(() => _userEmailer.TryToSendSubscriptionAssignedToAnotherEmail(tenant.Id, utcNow, edition.ExpiringEditionId.Value));
                    }
                }
                catch (Exception exception)
                {
                    failedTenancyNames.Add(tenant.TenancyName);
                    Logger.Error($"Subscription of tenant {tenant.TenancyName} has been expired but tenant couldn't be made passive !");
                    Logger.Error(exception.Message, exception);
                }
            } */

            if (!failedTenancyNames.Any())
            {
                return;
            }

            _userEmailer.TryToSendFailedSubscriptionTerminationsEmail(failedTenancyNames, utcNow);
        }
    }
}

    I have the same issue, but unclear if it actually has any impact. I usually just hit F5 to continue, and it seems to load the site with out any issues.

    Hi there

    thank you for that, however, we have already started our project, How can we apply changes you have made without losing our work?

    Regards Buddhi
