Yeah – I’m going to suggest that you update your instance.
“使用 ai 角色对帖子进行分类” doesn’t exist any more from what I can see in the codebase, I believe it’s a simple term change to “使用 AI 智能体对帖子进行分类”.
Regarding your issue, the automation plugin notoriously has always had idempotency issues. If you update, you should consider switching this “automation” to a “workflow” via the new workflow plugin.
