GraphQLとrailsでユーザー同士のLike機能を実現したい

Question

実現したいこと

あるユーザーがどのユーザーに対してLikeをしたのか、その情報を保持させるLikeモデルをGraphQLで実装しています。
mutationでCreateLikeFromというメソッドをつくり、user_id: 1がuser_id: 3をLikeする実装をしたいです。
現在の下記のコードでは、クエリを投げてもエラーが出力されてしまいます。

• クエリ

mutation {
  createLikeFrom(
    input:{userId: 1, toUserId: 3}
  ){
    likes {
      id
      fromUser {
        id
      }
      toUser {
        id
      }
    }
  }
}

どのあたりに問題があるかご教授いただきたいです。
