### 前提・実現したいこと

現在、[この記事](https://qiita.com/cigalecigales/items/f4274088f20832252374)を参考に個人開発のWebアプリで、twitterアカウントを使ったサインアップ機構とログイン機構を作成しています。ですがtwitter
Developersのcallbackの設定が分からず詰まっています。記事によって情報がバラバラで何のリンクで設定したら良いのか全く分かりません。とりあえず[この方の記事](https://saruwakakun.com/memo/omniauth-
twitter)をもとに

<http://127.0.0.1:3000/users/auth/twitter/callback>  
<http://localhost:3000/users/auth/twitter/callback>

を追加したのですが以下のようなエラーが出てしまいます。  
callback URLは現在何にすればいいのでしょうか  
回答よろしくお願いします。
