Every time I visit the admin groupware page in Nextcloud 28.0.5 with the Mail app installed I get two warnings in my Nextcloud log:
Invalid google_oauth_client_id data provided to provideInitialState by mail
Invalid microsoft_oauth_client_id data provided to provideInitialState by mail
I couldn’t find out anything about these warnings. They were mentioned in a Nextcloud Mail bug report but it turned out that they had nothing to do with the problem of the reporter.
It’s only a warning, I know. But I just don’t understand what Nextcloud Mail is trying to tell me with that… I’m not interested in Microsoft or Google mail integration and I didn’t (and don’t plan to) provide any client IDs etc. So I guess I see these warnings because I didn’t provide any client IDs?
