Conf.Language(29) (localized subscription-required message)

Error message

Conf.Language(29) (localized subscription-required message)

What it means

SetCloudReminder requires an active SiYuan subscription. When the user is not a subscriber and the container is not iOS, it returns the generic localized subscription-required message from Conf.Language(29). Same entitlement guard as the iOS variant, applied to desktop, mobile (non-iOS), and other containers.

Solutions

Purchase or renew the SiYuan subscription and ensure the account is logged in
Use local reminder mechanisms or skip cloud reminder sync for non-subscriber accounts
Check IsSubscriber-equivalent state client-side before calling setCloudReminder and show the upgrade prompt (Language 29)

Example fix

// before
await fetchPost('/api/block/setCloudReminder', {id, content, timed});
// after
const sub = await fetchPost('/api/account/...', {}); // check subscription state first
if (!sub.data.isSubscriber) {
  showMessage(window.siyuan.languages[29]); // prompt upgrade instead of erroring
  return;
}
await fetchPost('/api/block/setCloudReminder', {id, content, timed});

Defensive patterns

Strategy: try-catch

Validate before calling

if (!window.siyuan.user || subscriptionExpired(window.siyuan.user)) {
  showMessage(window.siyuan.languages[29]);
  return;
}

Try / catch

try {
  await fetchPost('/api/block/setCloudReminder', {id, content, timed});
} catch (e) {
  if (String(e.msg || e) === window.siyuan.languages[29]) {
    openMembershipDialog(); // prompt upgrade once, no retry
    return;
  }
  throw e;
}

Prevention

Gate cloud reminder calls on the logged-in user's subscription state
Treat this error as a permanent condition until the subscription is renewed
Provide local reminder alternatives in plugins aimed at non-subscriber users

When it happens

Trigger: Calling SetCloudReminder (API /api/block/setCloudReminder) without an active subscription on desktop or non-iOS mobile — e.g. a plugin or script setting a cloud reminder while logged out or with an expired subscription.

Common situations: Self-hosted/desktop users without membership invoking the cloud reminder API via automation; subscription lapsing between calls; scripts assuming reminder sync is free.
