最後の Ok(Json.obj("users" -> users)) の箇所のimplicitが見つからないみたい?
ドキュメント通りにimport JsonController._を書いてあるがダメ。

  def list = Action { implicit request =>
    val u = Users.syntax("u")

    DB.readOnly { implicit session =>
      // ユーザのリストを取得
      val users = withSQL {
        select.from(Users as u).orderBy(u.id.asc)
      }.map(Users(u.resultName)).list.apply()

      // ユーザの一覧をJSONで返す
      Ok(Json.obj("users" -> users))
    }
  }

元ソース

"""{"users":[{"id":1,"name":"Taro Yamada","companyId":1},{"id":2,"name":"Jiro Sato"}]}"""

下記のように"companyId":nullを明記すると通る。nullを返すかどうかなのでバージョンや設定が関係しているかも?

"""{"users":[{"id":1,"name":"Taro Yamada","companyId":1},{"id":2,"name":"Jiro Sato","companyId":null}]}"""
