Что может вызывать ошибки 500 при сохранении настроек пользователя?

[tkrunning (Thomas K. Running)]

За последние несколько дней я столкнулся с ещё одной странной ошибкой на моём экземпляре Discourse. Я не могу сохранить какие-либо настройки пользователя для своей учётной записи администратора — получаю только ошибки 500. Похоже, то же самое происходит с любым запросом PUT к u/[МОЙ_ПОЛЬЗОВАТЕЛЬ].json.

Я также попытался повторить тот же запрос в Postman, используя действительный API-ключ, но это тоже не сработало:

В логах (/logs) я тоже не вижу никаких ошибок.

Другие учётные записи, по-видимому, не затронуты, по крайней мере те, которые я проверял.

Вчера я обновил Discourse до последней версии, но проблема присутствовала и до обновления.

Есть ли какие-либо идеи, как продолжить отладку этой проблемы?

Если вы перейдете по адресу /logs на вашем экземпляре Discourse, будучи авторизованным как администратор, там должны отображаться дополнительные детали об ошибках, подобных этой. Если вы сможете поделиться содержимым вкладок «info» и «backtrace» для соответствующей ошибки, это поможет нам найти причину проблемы.

Редактирование: О, я вижу, вы уже там посмотрели . Не могли бы вы еще раз проверить, что все типы ошибок включены в нижнем левом углу страницы /logs?

Так что, возможно, это действительно была эта ошибка:

Я думал, что она появлялась из-за этой проблемы:

Composer previews not working in Safari

Now only one error showed up, but here it is expanded: [CleanShot 2023-08-03 at 09.53.18@2x] However, that might be a good hint, as I also ran into this Safari issue when adding in a regex with negative lookbehind recently. My Safari is at 16.3. I’ll try upgrading it to 16.6 and see if that solves it. EDIT: I see that negative lookbehinds are only supported from 16.4, so the update should be likely to fix my previous issue—let’s see if this issue is related. However, I’m a bit concerned tha…

Однако оказалось, что всё связано.

Удаление регулярного выражения из раздела «Следим за словами» > «Ссылка» решает проблему. Однако это означает, что следующая проблема всё ещё не решена:

Negative lookbehind not working in watched words regex

Interestingly, it seems to be browser-dependent. I get the error in Safari, but not in Chrome. When adding it in Chrome and viewing the list in Safari the error shows up there. But I guess I can just ignore it for now.

Обратите внимание, что регулярное выражение корректно согласно стандарту ECMA 2018, но, возможно, не соответствует стандарту регулярных выражений Ruby?

Регулярное выражение также работает как положено для сообщений на форуме.
