Invalid microsoft_oauth_client_id data provided to provideInitialState by mail

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?

Hello,

I’m searching the why too.

I’ve the same problem.

What’s the news about please?

I’m sorry, I have no news… I had some serious problems with the Mail app too, so I decided to stay with Roundcube as my webmail client at this time and give Nextcloud Mail another try later.
