小程序-云开发，云数据库中有也有数据。在select查询获取记录是报错。并且数据库集合权限也已经设置为：所以用户可读，创建者可读写

代码如下：

                   news.doc(id).get().then((res)=>{console.log(res)})

                   news.doc(id).get({

                        success:res=>{

                                this.setData({

                                        article:res.data,

                                        isAdd:false

                                })

                                wx.hideLoading()

                        }

                })

控制台提示错误信息：WAService.js:1 Uncaught (in promise) Error: errCode: -1  | errMsg: document.get:fail Error: cannot find document with _id 3, please make sure that the document exists and you have the corresponding access permission; at document.get api; 

因为调调用没反应 所以加了一行调试信息（第一行） 也是一样的错误
