Show errors when saving /login/settings page
Currently you don't get an error when you save the /login/settings page and it doesn't succeed.
Steps to reproduce:
- Create a user, go to /login/settings and set a username for it
- Create another user, go to /login/settings and try to set the same username.
Expected result:
error
Actual result:
You don't get an error. It shows the username you tried to save. But when you open the page again with a different (or no) flow ID, you'll see that the username wasn't saved because the field is now empty.
