`/admin/docker/repos`をロードしようとするとエラーコード: 500エラー

[Milenski (Milen Valov)]

Discourseで何が起こっているのでしょうか？アップデートのために管理ページを読み込もうとすると、「/admin/docker/repos を読み込もうとしている間にエラーが発生しました エラーコード: 500 error」というエラーが表示されます。

以前、新しいプラグインが実装され、システムにもインストールされたときに同様のことが発生したのを覚えています。しかし、現在インストールされているプラグインはなく、実装されているものしか使用していません。

以下を実行しました。

cd /var/discourse
./launcher rebuild app

すべて順調に進みましたが、管理パネルのアップデートページで同じエラーが再び発生します。

/logs からのバックトレースもここに示します。

この件について何かご存知の方がいらっしゃいましたら、ご協力いただけると幸いです。

[david (David Taylor)]

ご報告ありがとうございます。修正対応中です。

FIX: Restore `Discourse::Version::PRE`

latestで利用可能になり次第、こちらに再度投稿します。

[bananaman]

本日アップデートをインストールした後も同じエラーが発生しており、リビルドしても解決しませんでした。
昨日アップデートは正常にインストールされ、このエラーは以前には見られませんでした。

私もこの問題が発生しました。2回リビルドしても解決せず、修正を待っています。

[david (David Taylor)]

遅くなり申し訳ありません。本日、いくつかの無関係なCIの問題が発生しました。

修正は現在latestで公開されていますので、再度アップデートすることで問題が解決するはずです。解決しない場合はお知らせください。

[Milenski (Milen Valov)]

確認しました、問題は解決しました。ターミナル経由で再構築した後、すべて順調です。ありがとうございます。
