@demox - You are right. I need to log in.
@dexmox: Your link... https://github.com/aspnetzero/aspnet-zero/issues/96#issuecomment-268093697 ...is broken. Error 404.
The job runs to completion (several minutes) and completes normally.
Abp v4.9.0 ANZ v7.2.3 Core/Angular Background jobs are not disabled. I use them in my app.
After upgrading Visual Studio Enterprise 2019 to version 16.3.5 and Visual Studio Code to version 1.39.2 the problem disappeared. I have no explanation of how or if upgrading VSs fixed the problem.
Your solution worked. Thank you!
ANZ version 7.2.3 Sent project link via email.
Upgrading to Core 2.2.6 fixed the issue.
Discovered 5 rows in AbpTenantNotifications table with "PubExamStatus". Deleted 5 rows. The error is not appearing. Fixed.
