正在从其他服务器，将用户数据迁移到云开发，没想到遇到这个致命的BUG，尽快解决

在小程序上通过add操作自定义的_id，无法使用eq进行查询，在聚合操作中id也无法关联查询到。

  add(e) {
    db.collection('lab')
      .add({
        data: {
          _id: "5c403b51170fbe0b046280ae",
          team: ['193509428'],
          name: 'demo',
          show: true
        }
      }).then(res=>{
        console.log(res)
      })
  },
  get(){
    db.collection('lab').where({
      _id:_.eq('5c403b51170fbe0b046280ae')
    }).get().then(res=>{
      console.log(res)
    })

}
