您好，Discourse 团队！
我在尝试将分类从暂存环境导出到生产环境时遇到了一个错误。为了方便起见，我们在暂存环境中有很多主题希望发布到生产环境中，而复制粘贴会花费很长时间。
这是我在运行 discourse import_category category-export-2022-02-14-042606.json（基于此教程）后遇到的错误：
Starting import from category-export-2022-02-14-042606.json...
Importing users...
Importing groups...

我只想导出分类，所以我不太确定它为什么会抱怨组。
非常感谢任何帮助！
祝好，
