[Kemono] extractor.kemono.archives html only contain None

I wanted to save zip file password and file list, but when i use
`{"extractor": {
    "kemono":{
            "directory":["{category}","{service}","{user_profile['id']} {user_profile['name']}"],
            "archives": true 
    }
}
}`
it downloaded .html file that inside contain nothing but the word "None".
Other files downloaded fine so I'm wondering how it works.
