Error message

The sidebar feature that comes with the plugin needs to be configured on the desktop (you can access http://127.0.0.1:6806/stage/build/desktop using a mobile browser, after the configuration is complete, please restart SiYuan APP)

What it means

Returned by SetCloudReminder when util.Container == "ios" and IsSubscriber() is false. Conf.Language(122) is the iOS-specific message instructing the user that the sidebar/cloud feature must be configured on desktop. iOS App Store policy requires routing such features through subscription, so the kernel gates them on iOS.

Solutions

Purchase the annual subscription and refresh login in Settings - Account & Sync.
Perform the operation on desktop (or via the desktop endpoint from a mobile browser) where the iOS gate does not apply.
Refresh account state (Settings - Account & Sync - Account) if recently subscribed.

Defensive patterns

Strategy: validation

Validate before calling

if util.Container == "ios" && !model.IsSubscriber() {
    return errors.New("cloud reminders on iOS require a subscription")
}

Prevention

Gate the SetCloudReminder UI affordance on subscription status when running on iOS.
Prompt the user to subscribe before the call rather than after.
Offer a desktop flow as a fallback on iOS.

When it happens

Trigger: Calling SetCloudReminder from the iOS build without an active subscription; calling from a non-subscriber iOS session.

Common situations: User on iOS attempting to set a cloud-based reminder; iOS user whose subscription expired; iOS user logged out of their account.
