Cosa potrebbe causare errori 500 durante il salvataggio delle preferenze utente?

[tkrunning (Thomas K. Running)]

Negli ultimi giorni ho riscontrato un altro strano bug nella mia istanza Discourse. Non riesco a salvare alcuna preferenza utente per il mio utente amministratore, ricevo solo errori 500. Sembra essere lo stesso per qualsiasi richiesta PUT a u/[IL_MIO_USERNAME].json.

Ho anche provato a ripetere la stessa richiesta in Postman utilizzando una chiave API valida, ma anche quella è fallita:

Non vedo errori nemmeno in /logs.

Altri account utente non sembrano essere interessati, almeno quelli che ho provato.

Ho aggiornato Discourse all’ultima versione ieri, ma il problema era presente anche prima dell’aggiornamento.

Qualche idea su come posso continuare a eseguire il debug di questo problema?

Se visiti /logs sulla tua istanza Discourse mentre sei connesso come amministratore, dovresti vedere maggiori dettagli su errori come questo. Se puoi condividere il contenuto delle schede ‘info’ e ‘backtrace’ per l’errore pertinente, questo ci aiuterà a individuare il problema.

Modifica: oh, vedo che hai già controllato lì . Potresti ricontrollare che tutti i tipi di errore siano abilitati in basso a sinistra in /logs?

Quindi immagino che in realtà potesse essere questo errore:

Pensavo che apparisse semplicemente a causa di questo 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…

Tuttavia, si è scoperto che sono tutti correlati.

Rimuovendo l’espressione regolare da Parole monitorate > Link si risolve il problema. Tuttavia, questo significa che il problema seguente rimane irrisolto:

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.

Si noti che l’espressione regolare è valida secondo lo standard ECMA 2018, ma forse non secondo lo standard delle espressioni regolari di Ruby?

L’espressione regolare funziona anche come previsto per i post sul forum.
