rails tutorial 11.41 heroku でのユーザー登録でのエラー

Question

rails tutorial 11.41で
rails sコマンドを使用した開発環境ではエラー無く処理できるのですが、
heroku にデプロイした環境だとユーザー登録時に、

We're sorry, but something went wrong.
If you are the application owner check the logs for more information.

と表示されます。
その後、データベースを確認するとユーザーは登録されているのですが、何が原因でエラーが発生しているのかわかりません。しばらく調べていたのですが、行き詰ってしまったため、ご教授頂けると幸いです。

↓ heroku logs --tails を実行してユーザー登録した時の表示

調べてみたところsendgridからbanされていました。
問い合わせしてみたいと思います。
ありがとうございます。
