自分でも調べているのですが、いまいち原因がわからなかったので、質問させていただきました。
ご教示の喉よろしくお願いいたします。

※追記です。
 NameError: undefined local variable or method `otetsudainetto' for <Otetsudai::Application:0x0055c997390358>の
『otetsudainetto』を捜しているのですが、まったく見当たりません。
そもそも、、そのような変数、メソッドにおぼえがありません。
以前、otetsudainettoというアプリを開発していて挫折してしまい、今回はnewotetsudainetto
と名前を変えて挑戦しています。
変な話なのですが、どこを探していけば、このエラー元『otetsudainetto』を発見できるのでしょうか？
自分で探せよという話ですが、簡単なアドバイスでいいので、ご回答お待ちしております。

Answer 1

とりあえず、探し方の提案として
git grep -P "(?<!new)otetsudainetto"
でリポジトリ内の管理しているファイルを検索できます。

ただ、なんとなく環境変数なども調べる必要があるかな？と思います
heroku configで一覧が取れるようです

git grep便利ですね...。初めてしりました。大変勉強になります。
色々と調べた結果、sendgridを使うために設定した
host = 'polar-hollows-53728.herokuapp.com'
config.action_mailer.default_url_options = { host: polar-hollows-53728.herokuapp.com }
の記述の仕方が間違っておりました。
以前は、polar-hollows-53728ではなく、otetsudainetoがhost名だったため、それも輪をかけてわからなくなってしまいました。
ご協力いただきありがとうございました。

Answer 2

とりあえず質問文からは「otetsudainetto」という変数もしくはメソッドはないよと
いうのが読み取れます。
それを書いているあたりを見直してみましょう。

なんどか探してはいますが、まさかの見当たりません、、、。
そもそも，そんな変数、メソッドに覚えがないので、苦戦しております、。

たしかに見た感じ使われてなさそうですね。
asm様の仰るように環境変数の問題などかもしれません。
