GraphQL 查询 subject relations 缺失

[Him188]

https://api.bgm.tv/v0/graphql

query BatchGetSubjectQuery {
  s0:subject(id: 407573) {
    relations {
      relation
      subject{id}
      order
    }
  }
}

Actual response

只有一个关联条目 (小说)

{
  "data": {
    "s0": {
      "relations": [
        {
          "relation": 1,
          "subject": {
            "id": 124785
          },
          "order": 0
        }
      ]
    }
  }
}

Expected

Bangumi 网站上有很多: https://bangumi.tv/subject/407573

Archive 的数据库里也有很多
