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

kernel/model/blockial.go:43, from SetCloudReminder: the cloud reminder feature requires an active subscription (IsSubscriber() false). On the iOS container specifically, the kernel returns language key 122, whose shipped English text is the generic mobile-restriction message about configuring plugin sidebars via the desktop endpoint (http://127.0.0.1:6806/stage/build/desktop) and restarting - the message is only loosely related; semantically it means 'this account/feature is not available in the iOS app here'.

Solutions

Log in with an active subscription account (purchase via the subscription page).
If already purchased: refresh or re-login under Settings - Account & Sync - Account, then retry.
If stuck on iOS, complete/refresh the subscription from the desktop app with the same account, then retry on iOS.
For local-only automation, avoid the cloud-reminder API and use local reminders instead.

Defensive patterns

Strategy: try-catch

Try / catch

try {
  await setCloudReminder(id, content, timed);
} catch (e) {
  if (/subscribe|Annual Subscription|sidebar feature/i.test(e.message)) {
    // entitlement problem, not a bug: prompt login/purchase, do not retry
    promptSubscription();
  } else throw e;
}

Prevention

Gate cloud-reminder calls behind an account/subscription check in your integration UI.
Do not auto-retry entitlement errors - they never succeed without user action.

When it happens

Trigger: Invoking the cloud reminder flow from the SiYuan iOS app while not logged in as an active subscriber: the corresponding HTTP endpoint behind cloud reminders with a non-subscription account and util.Container == 'ios'.

Common situations: Testing API automation against an iOS build with a free account; users who subscribed on desktop but are not logged into the same account on iOS; App Store policy builds where purchase/refresh must happen outside the app.
