Herokuでデプロイ完了後 アプリを開くとapplication errorが帰ってくる

Question

ruby on rails チュートリアルを使って練習中です。
第２章のアプリ、を実装、ローカルで問題なく作動したので、Herokuへデプロイ。
その際、herokuのbundlerがversion1.16に対応していなかったので、1.15.2に戻しHerokuへデプロイしたところ、herokuの管理画面では正常に完了したと表示されました。
しかし、Open appボタンからページを開いたところ、Application error が発生し、logを読んでもその対策がわからないので、同じ状況を経験した方などお教えいただけますと幸いですm(_ _)m

heroku logs コマンドでherokuサーバ側のログが取れるのでそれを貼って頂きたいです。

heroku logsありがとうございます。

DBにusersテーブルが存在しないというエラーが出ているようですね。
ローカル環境で動いていたのであればマイグレーションファイルは作っているはずなので、

heroku run rails db:migrate

を実行してみて下さい。
