Rails 7 + Devise + Turbo stream not showing errors when sign in

Question

I started new project and am stuck for hours trying to make Sign In page show errors. Though when I try to write incorrect data on Sign up page it returns errors, Sign in completely ignores it. I found decision concerning devise for rails 7 from gorails , it didn't help.

Gemfile:

gem "devise", git: "https://github.com/ghiculescu/devise.git", branch: "error-code-422"
gem "responders", git: "https://github.com/heartcombo/responders.git"

config/initializers/devise.rb:

Devise.setup do |config|
...
config.navigational_formats = ['*/*', :html, :turbo_stream]
...

Did it in order not to add new controller and custom error as it was shown in video. Also, console returns 422, but in terminal still:

My views are default generated by devise. If I should provide more info, like application.html.haml etc, please tell me.

This is a known issue with Devise, and for now the recommended fix is to disable Turbo on Devise's log in/out forms.

From https://github.com/heartcombo/devise/wiki/Troubleshooting-Rails-7-and-Turbo-Drive :

Since Turbolinks is replaced with Turbo Drive (That is part of Hotwire), we need to ensure full-page redirects when submitting devise forms.

One trick you can use for Devise's log out link, since it uses the HTTP DELETE method, is to change it to a button, like so:

<%= button_to "Log out", destroy_user_session_path, method: :delete, data: { turbo: false } %>

... but the wiki link above has other samples as well.

There are some more details and discussions here:
