サーバーエラー
/groups/.json の読み込み中にエラーが発生しました
エラーコード: 500 Internal Server Error
ログによると、report_js_error が報告されています。
グループ機能が停止しているため、これは深刻な問題です。問題の解決方法に関する手がかりがあれば幸いです。よろしくお願いいたします。
問題がより深刻化しました。現在、トピックを読み込めません。次のエラーメッセージが表示されます：
申し訳ありませんが、そのトピックを読み込めませんでした。接続の問題が原因の可能性があります。もう一度お試しください。問題が解決しない場合は、ご連絡ください。
安全モードを試しましたか？また、ログも確認し、おそらくそれらを提示する必要があります。
それらを行っても私個人ではお手伝いできませんが、これら2つのことを試さなければ、誰にもお役に立てることはほとんどありません。
私の個人でホストしているインスタンスと、私が管理しているCDCKホストのインスタンスの両方は、最新バージョンでグループのJSONファイルを問題なく読み込んでいます（さっき確認しました）。
以下は、繰り返し発生しているエラーの一例です：

ありがとうございます。セーフモードで試しても同じエラーが発生しました。プラグインのコメントアウト後にコンテナを再構築する必要がありますか？
セーフモードでプラグインを無効にしても問題が解決しなかった場合、プラグインをコメントアウトする必要はないと思います。ただし、アップグレードと再構築で解決するかもしれません。
ありがとうございます。トピックを投稿する前に launcher rebuild image-name を実行しましたが、エラーは解消されませんでした。
それは ./launcher rebuild app と同じ役割を果たしますか？
その通りだと思います。‘app’ という名前のコンテナが作成されるはずです。
ああ、なるほど。残念ながら、私には「電源を切って、もう一度入れる」という基本的な手順しかわかりません。
あなたのインストール環境に、他の人が問題のヒントを得られるような特別な点はありますか？
以下のファイルが不足しているようです。
これは以下のコミットで導入されました。
保存できました。これで解決です。最新バージョン（aba08d1929）にアップグレードしたところ、問題が解消されました。ただし、最新のリリース版（2.8.0.beta6）ではこの問題は解決されませんでした。
なぜ、現在運用している他のすべての Discourse インスタンス（すべて 2.8.0.beta6）ではこの問題が発生しなかったのか、不思議に思っています。
