caldav_oauth_unsupported

Error message

CalDAV does not support OAuth authorization.

What it means

CalDAVProvider.getAuthUrl always throws caldav_oauth_unsupported because CalDAV uses basic credentials rather than OAuth; calling the OAuth entry point for this provider is an API misuse the type system does not prevent.

Solutions

1. CalDAV uses basic authentication (username and app password); do not select OAuth for a CalDAV provider.
2. Reconnect the calendar using the CalDAV basic-auth flow instead of the OAuth button.
3. If you need OAuth, choose a provider that supports it (e.g. Google) instead of generic CalDAV.
