Thanks. Now the import\_users passed, but now it failed on import\_categories when executing

```
raw = process_discuzx_post(row['rules'], nil)
          if @bbcode_to_md
            raw = raw.bbcode_to_md(false) rescue raw
          end
          category.topic.posts.first.update_attribute(:raw, raw)

```

with error

```
