Как мне получить сообщения об ошибках входа в Ruby on Rails 5.2?

Question

Я использую Ruby на рельсах 5.2 с Mysql и Puma.Когда я пытаюсь ввести неверную информацию в окне проверки входа в систему, я не получаю никаких ошибок.Вместо этого я получаю кнопки, которые я могу нажимать, но ничего не делать.Если я вернусь на домашнюю страницу, то появится сообщение об ошибке, независимо от того, были ли flash.now или сообщения об ошибках flash.Я знаю, что отключение турбо-ссылок ничего не делает.

Я понятия не имею, почему это происходит, но это связано с 5.0, так как эта проблема не возникает в рельсах 3.2.14.Любой совет?
