Post #9797

Innei 向 mx-space/core 提交了一个更改 fix(category): handle null category in category service - Added a null check for the category in the CategoryService to return null if the category is not found. - Updated PostService to use category._id or category.id for categoryId assignment when creating a new post. - Imported extractDocumentContext in lexical-translation-parser tests for improved utility access.
