Concurrency Check does not work as described in docs #3152

  • DB provider: EF Core
  • Tiered (MVC) or Identity Server Separated (Angular): no

I am testing behaviour of Concurrency Check. I followed the implementation described in docs. However, when there's conflict with concurrency stamps I do not get the expected error modal in my client (Angular) app. All I get is error page with "Unknown Error" message even though I see a 409 response in developer tools:

I found that this happens only when I call UpdateAsync on the repository exactly like in the documentation i.e. without autoSave: true parameter. When I add the autoSave: true parameter or call CurrentUnitOfWork.SaveChangesAsync() at the end I get expected error modal. My question is - is the documentation wrong for not pointing out that saving changes is required or is there something wrong in my implementation?

    hi

    Can you share the error logs of HTTP status code 409?

    Also try to remove the app.UseUnitOfWork(); from the web project.
