@darkpixlz 현재 사용 중인 Discourse 버전이 무엇인지 확인해 주시겠어요? stable, beta, tests-passed 중 어느 것인가요?

현재 베타 버전 2.9.0beta7을 실행 중입니다. 커밋이 2개 뒤처져 있지만, 해당 문제는 커밋과 무관합니다.

방금 이 커밋을 core에 push했습니다:
>
>
> See https://meta.discourse.org/t/232885 for context. This rake task enumerates p…roblematic records and prints out a sample of each failure.
이 커밋은 이 문제를 추적하는 데 도움이 될 새로운 rake 작업을 도입합니다. 저희 호스팅 환경에서는 어떤 에러도 발생하지 않고 있으므로, 이는 서드파티 플러그인과 관련이 있을 가능성이 높습니다.
문제를 겪고 있는 분이 있다면 최신 tests-passed 버전으로 업데이트한 후 다음을 실행해 주세요:
```bash
./launcher enter app
cd /var/www/discourse
bin/rake "revisions:debug_deserialization"
```
이 작업은 문제의 클래스에 대한 정보와 각 클래스에 대한 예시 리비전을 출력합니다. 출력 결과의 요약/예시 섹션을 이 토픽에 공유해 주세요 (예시 리비전을 공개적으로 공유하고 싶지 않으시면 개인 메시지로 보내셔도 됩니다).
문제의 원인이 정확히 무엇인지 알게 되면 수정 작업을 진행하는 데 도움이 될 것입니다. (수정 방법은 서드파티 플러그인의 데이터베이스 마이그레이션이거나, 예상치 못한 데이터를 정리할 수 있는 core rake 작업이 될 가능성이 높습니다)

여러분 안녕하세요,
불행히도 이 스레드에서 시간을 낭비했습니다…

그래서 최신 빌드로 업데이트했지만 여전히 문제가 발생합니다.

실행을 시도해 보았지만 제 환경 설정 때문에 여기서 도움을 드릴 수 없는 것 같습니다:
저는 docker / postgres 안에서 실행하고 있습니다.
이 문제를 해결하는 데 도움이 될 다른 조치가 있을까요?
제가 사용 중인 플러그인은 다음과 같습니다.

환경 변수를 설정해야 합니다 … `bin/rake` 대신 `rake`를 사용해 보세요

아, `./launcher enter app`을 실행했다면 `root` 권한으로 로그인됩니다. 데이터베이스에 접근하려면 `discourse` 사용자로 전환해야 합니다. 다음 명령을 실행해 보세요:
```plaintext
sudo -EH -u discourse bin/rake "revisions:debug_deserialization"

아! 예상치 못한 일이네요!
일부 게시물 수정 내역을 볼 때에도 여전히 오류가 표시되고 있나요?
참고로, 이건 ‘표준 설치’ 환경인가요, 아니면 멀티사이트 클러스터에 호스팅된 건가요?

네, 표준입니다.
그리고 더 이상 그런 건 아닌 것 같네요. 한동안 알아채지 못했는데, 이제 해결된 것 같습니다.

네, 좋습니다. @darkpixlz 감사합니다.
@B-iggy [이 게시물](https://meta.discourse.org/t/problem-with-post-revisions-after-updating-to-2-8-6-stable-or-2-9-0-beta7/232885/33?u=david)에 있는 명령어를 한번 시도해 볼 수 있을까요? 처음 보셨던 오류가 해결될 것 같습니다 🤞

하지만 안타깝게도 [여기](https://forum.empyrion-homeworld.net/t/orbital-cargo-drone-ocd/4394) 있는 해당 토픽의 내 수정 이력은 여전히 비어 있습니다. 죄송합니다. 다른 로그를 제공할 수 있을까요?

@B-iggy 감사합니다. 정말 놀랍네요 - 스크립트가 오류 목록을 표시할 거라고 생각했어요. 🤔
자신의 사이트에서 `/logs` 경로를 방문해서 최근 오류 로그가 있는지 확인해 주시겠어요? 특히 `Psych::DisallowedClass`로 시작하는 로그를 찾고 있습니다.

네. Psych 오류가 여러 개 있습니다.
어떤 것이 필요하신가요? 🙂

감사합니다, 도움이 되네요! 이 명령어를 실행해 보고 출력을 붙여넣어 주시겠어요?
```plaintext
sudo -EH -u discourse bin/rails runner "puts PostRevisor.tracked_topic_fields.inspect"
```
이렇게 하면 PostRevisions에 데이터를 추가하는 플러그인을 파악하는 데 도움이 될 거예요. 🤞
제 로컬 사이트에서는 다음과 같이 반환됩니다.
```plaintext
{:title=>#, :archetype=>#, :category_id=>#, :tags=>#, :featured_link=>#}
```

정말 감사합니다!
제 출력 결과는 다음과 같습니다.

@B-iggy와 저는 개인 메시지로 이 문제를 조사해 원인을 찾았습니다. 해당 주제에는 오래된 태그가 붙어 있었지만, 사이트에서는 태그 기능이 비활성화되어 있었습니다. 이 두 가지 요인이 결합되어 코어에서 이상한 엣지 조건을 유발했고, 이로 인해 오류가 발생했습니다. 해당 문제는 다음 커밋으로 해결되어야 합니다.

다른 문제가 여전히 있을 수 있으므로, 이 주제를 몇 주 더 열어둘 것입니다. 리비전 로딩 시 여전히 문제가 발생한다면 알려주세요.
