railsで作った簡単なサイトにdeviseで会員登録とログイン機能を実装したいが、sign-up,log-in両画面に移動できない

前提・実現したいこと

ここに質問の内容を詳しく書いてください。
railsを勉強している初心者です。今回、簡単な本の感想投稿サイトにdeviseを用いて会員登録とログイン機能を実装しようと思ったのですが、deviseフォルダの記述を少し変更していたところ、urlを指定しても会員登録・ログイン画面の両方に移動できなくなってしまいました。

発生している問題・エラーメッセージ

urlにてusers/sign_inと入れても、deviseの会員登録・ログイン画面に移動できない。
以下ターミナルの出力です。

該当のソースコード　変更した点

20210101103335_devise_create_users.rb　最後部あたり　t.string :name追加

      t.string :name
      t.timestamps null: false
