railsのDeviseエラーについて<Completed 401 Unauthorized>

Question

###前提・実現したいこと

railsのGem"devise"を用いてログイン、ログアウト機能を実装しようとすると、emailとpasswordの二つしかできませんが、ここにユーザーネームも加えたいと思いました。

$ rails g migration add_name_to_users name

でmigrationファイルを作成して、マイグレーションファイル等々を編集して、実行しました。

###発生している問題・エラーメッセージ
3000は無事に立ち上がり、新規登録<sign_up>とログアウトはできるのですが、ログイン<sign_in>ができません。
具体的なエラーメッセージは表示されず、ターミナルに以下のようなものが出てきます。

おそらく、このComplete 401 Unauthorized in...というのがエラーだと思われます。

Answer 1

あまり詳しくはありませんが、emailとnameを使ってログインするのか、emailまたは、nameでログインするかが読み取れなくて、 config/devise.rbだと前者で、viewをみると後者に読み取れまして、どちらか迷っていまして、問題の特定まではできないなーという感じです。

前者であればこちらのリンクが参考になるかもしれません。
