herokuでデプロイしたrailsアプリが正しく表示されない

Question

herokuでRailsアプリをデプロイしたのですが、そのURLにアクセスすると

どうしても文字数制限で全てはお見せできないので、真ん中あたりを削除しました。
調べてもわからず、詰まっています。
よろしくおねがいします！

ローカル環境では、production モードで問題なく動作していますか？

[aspot_0734]

はい

[aspot_0734]

やっぱり動作してないかもです。確認します。

[aspot_0734]

今日また同じコードを実行すると、昨日と表示が変わっていました。

[hoshi-takanori]

heroku logs --tail は特に何かを実行するのではなく、保存されているログを表示するコマンドです。
で、最初半分を削除したとのことですが、むしろそこが重要なので、その前の部分も載せてください。

[aspot_0734]

コードの量が多く、どうしても文字数制限がかかってしまうのですが、削除していい場所などありますか？

[nskydiving]

コードではなく、ログですか？
どこを削除して良いか判断できないと思いますので、文字列制限に引っかかってしまう場合は、GitHub などの外部サービスに保存して、その URL を貼ってもらえば良いと思います。
