即使值存在，為什么物件鍵回傳undefined-有解無憂

我想訪問一個物件的密鑰，但它回傳未定義，我不知道為什么

這是我的代碼

const docs = await this.walletModel.find({
      status: 'Venus'
    }).select('user meteorite').populate('user', 'name extra.profilePic extra.thumbnail').lean()

    // @ts-ignore
    const userIds = docs.map(user => Types.ObjectId(user?.user?._id))

    const boughtUsers = await this.subscriptionModel.find({ user: { $in: userIds } }).select('-_id user')

    const reduced = docs.reduce((acc, curr) => {
      // @ts-ignore
      if (boughtUsers.some(boughtUser => {
        // @ts-ignore
        console.log(boughtUser, curr?.user?._id) // logging here

        // @ts-ignore
        return boughtUser?.user === curr?.user?._id
      })) return [...acc, {...curr}]

      return [...acc, {...curr, gift: true}]
    }, [])

    return reduced

它回傳

即使值存在，為什么物件鍵回傳 undefined

如您所見，有用戶密鑰，但是當我嘗試記錄它時，它回傳未定義

const docs = await this.walletModel.find({
      status: 'Venus'
    }).select('user meteorite').populate('user', 'name extra.profilePic extra.thumbnail').lean()

    // @ts-ignore
    const userIds = docs.map(user => Types.ObjectId(user?.user?._id))

    const boughtUsers = await this.subscriptionModel.find({ user: { $in: userIds } }).select('-_id user')

    const reduced = docs.reduce((acc, curr) => {
      // @ts-ignore
      if (boughtUsers.some(boughtUser => {
        // @ts-ignore
        console.log(boughtUser?.user, curr?.user?._id) // logging here

        // @ts-ignore
        return boughtUser?.user === curr?.user?._id
      })) return [...acc, {...curr}]

      return [...acc, {...curr, gift: true}]
    }, [])

    return reduced

我嘗試使用 Object.entries() 進行日志記錄，它回傳了類似的內容
