Error message

Trigger not found

What it means

Raised by POST /apps/{app_id}/trigger-enable when no AppTrigger row matches (trigger_id, current_tenant_id, app_id). The trigger must belong to the caller's tenant and the URL's app. Returned via flask_restx NotFound (HTTP 404).

Solutions

1. Refresh the trigger list via GET /apps/{app_id}/triggers and use a current trigger_id.
2. Confirm the trigger belongs to the same tenant and app as the URL before toggling.
3. If the trigger was removed, recreate it through the workflow studio Trigger panel.

const triggers = await get(`/apps/${appId}/triggers`);
const ok = triggers.data.some(t => t.id === triggerId);
if (!ok) { /* do not POST trigger-enable */ }

try {
  await post(`/apps/${appId}/trigger-enable`, { trigger_id: triggerId, enable_trigger: val });
} catch (e) {
  if (e.code === 404 && /trigger not found/i.test(e.message)) {
    // refresh trigger list, drop stale id
  } else { throw e; }
}

When it happens

Trigger: POST /console/api/apps/{app_id}/trigger-enable with body {trigger_id, enable_trigger} where trigger_id does not exist, belongs to another tenant, belongs to another app, or was deleted.

Common situations: Stale trigger_id in the UI after the trigger was removed; cross-tenant or cross-app reference; enabling a trigger on the wrong app after a copy; trigger row hard-deleted by a cleanup job.
