How to translate the error message into Japanese (What to do if you cannot log in for some reason)

How to translate error messages into Japanese

I can't hide my confusion about Markdown notation in my first post, but I'd like to gradually get used to it.

This time, when I tried to translate the error message into Japanese, I could not log in as a user by devise, so I would like to share how to solve it.

Development environment

Ruby 2.6.5 devise 4.7.3

I wrote the following code in each file. For some reason I got an error when I pasted the latest devise.en.yml file (ver.> = 4.2.0). Using the version below it (> = 3.4.0) solved it.

config/webpack/application.rb

module ChatDiary
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 6.0
    config.time_zone = 'Asia/Tokyo'
    config.i18n.default_locale = :ja
    config.i18n.load_path += Dir[Rails.root.join('config', 'locales', '**', '*.{rb,yml}').to_s]
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration can go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded after loading
    # the framework and any gems in your application.
  end
end

ruby:config/locales/devise.en.yml
