It looks like a [bug](https://bugs.ruby-lang.org/issues/18633) around
autosplat is [fixed](https://bugs.ruby-lang.org/projects/ruby-master/repository/git/revisions/fbaadd1cfe7fbfd1b904f193f99d7c845a6ed804)
on ruby-3.2.0-rc1 and breaks a test (but not on ruby <= 3.1.3):
```
$ bundle exec rspec ./spec/controllers/api/v1/emails/confirmations_controller_spec.rb:41
:
1) Api::V1::Emails::ConfirmationsController#create with an oauth token from an app that created the account when the account is already confirmed but user changed e-mail and has not confirmed it returns http success
Failure/Error:
def email_changed(user, **)
@resource = user
@instance = Rails.configuration.x.local_domain
return unless @resource.active_for_authentication?
I18n.with_locale(locale) do
mail to: @resource.email, subject: I18n.t('devise.mailer.email_changed.subject')
end
end
ArgumentError:
