I want to access key to an object but it returns undefined and I don't know why

This is my code

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

it returns

as you can see there are user keys but when I am trying to log it it returns undefined

code

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

returns
