Did you setup OneSignal to send Web Push Notifications? The discourse-onesignal plugin should only be used for iOS notifications, the screen above with the “Service Worker 404” error does not look like an iOS issue.
So, if you’re trying to set up OneSignal for an iOS app, the first step is good (installing the discourse-onesignal plugin), but the second step should be to start setting up the app according to the instructions in the repository at https://github.com/pmusaraj/discourse-mobile-single-site-app
qual è il sistema che collega l’ID utente di OneSignal con l’ID utente in Discourse?
Ho cercato, ma nella mia lista utenti su OneSignal non ci sono dati relativi all’utente di Discourse, e in Discourse non sono riuscito a trovare alcun riferimento all’utente di OneSignal.
