pq: null value in column "favorites_count" of relation "articles" violates not-null constraint

[Msksgm]

When I called the bellow api , this error of pq: null value in column "favorites_count" of relation "articles" violates not-null constraint is happend.

curl --location --request POST 'http://localhost:6001/api/v1/articles' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJlbWFpbCI6InNhbXBsZUBlbWFpbC5jb20iLCJpZCI6MX0.SZBUfkdrOBlmomrYzqNfjMBcjL9n8iwr948RsgJok1U' \
--data-raw '{
    "article": {
        "title": "title",
        "description": "description",
        "body": "body"
    }
}'

I think this bellow query is not correct, because the col of favorites_count is not included in the artcle table. When I deleted favorites_count and $6 and article.FavoritesCount, it is workd correctly
