This is because we haven't added/register to@GetMappinginside MainController. Let's fix it now. Once it is fixed, try to perform a registration from the register page. After registration, you should see the debug information thatUserRegisteredEventHandlercreated.

Not adding /register to the mapping reveals a defect in our end-to-end testing. The end-to-end test is supposed to capture this kind of issue during building. Unfortunately, it didn't. We will improve our end-to-end testing in the next chapter. The following is the commit record:
