O que pode estar causando erros 500 ao salvar preferências do usuário?

[tkrunning (Thomas K. Running)]

Encontrei outro bug estranho na minha instância do Discourse nos últimos dias. Não consigo salvar nenhuma preferência de usuário para meu próprio usuário administrador, recebo apenas erros 500. Parece ser o mesmo para qualquer solicitação PUT para u/[MEU_NOME_DE_USUÁRIO].json.

Também tentei repetir a mesma solicitação no Postman usando uma chave de API válida, mas isso também falhou:

Não vejo nenhum erro aparecendo em /logs também.

Outras contas de usuário não parecem ser afetadas, pelo menos as que tentei.

Atualizei o Discourse para a versão mais recente ontem, mas o problema já existia antes da atualização.

Alguma ideia de como posso continuar depurando isso?

Se você visitar /logs na sua instância do Discourse enquanto estiver logado como administrador, ele deverá mostrar mais detalhes sobre erros como este. Se você puder compartilhar o conteúdo das abas ‘info’ e ‘backtrace’ para o erro relevante, isso nos ajudará a rastrear o problema.

Editar: ah, vejo que você já olhou lá . Você poderia verificar novamente se todos os tipos de erro estão habilitados no canto inferior esquerdo de /logs?

Então, acho que na verdade pode ter sido esse erro:

Eu achei que aquele estivesse aparecendo apenas por causa deste problema:

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…

No entanto, acabou que tudo está relacionado.

Aqui estão os logs completos:

Remover a expressão regular de Palavras Monitoradas > Link resolve o problema. No entanto, isso significa que este problema ainda está sem solução:

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.

Observe que a expressão regular é válida de acordo com o padrão ECMA 2018, mas talvez não pelo padrão de expressões regulares do Ruby?

A expressão regular também funciona conforme o esperado para posts no fórum.
