代码如下：

{
  const db = wx.cloud.database()
  Page({
    data: {
    },
    onLoad: function () {
      db.collection('aaaaa').get({
        success: function (res) {
          console.log('轮播图获取成功', res)
        },
        fail: function (res) {
          console.log('轮播图获取失败', res)
        },
      })
    }
  });
}

具体报错信息如下：

简单的创建的集合，按照教程进行云数据库调用，环境变量应该是默认的（没搞明白怎么设置，直接默认的）。现在出现这个-501009报错，求解决方案0.0.
