Question

我的使用Mongoose的API有Micro个端点。除了使用.findOne（）的代码，其他所有代码都可以正常工作。这将在本地返回正确的数据，但在部署到Now v2时不会返回。这是端点：

const { createError, run, send } = require("micro");
const mongoose = require("mongoose").set("debug", true);
const mongooseConnect = require("./utils/mongooseConnect");
const Art = require("./schemas").art;
mongooseConnect();
const art = async (req, res) => {
  console.log("hello world");
  const id = req.url.split("id=")[1].split("&")[0];
  console.log("id", id);
  console.log("mongoose.Types.ObjectId(id)", mongoose.Types.ObjectId(id));
  try {
    const data = await Art.findOne({ _id: id });
    console.log("data", data);
    if (!data) {
      throw createError(404, "Item of art not found.");
    }
    send(res, 200, { data });
  } catch (error) {
    console.log(error);
    throw createError(error.statusCode, error.statusText);
  }
};
module.exports = (req, res) => run(req, res, art);

这是输出：

2019-05-25T02:07:12.706Z  hello world
2019-05-25T02:07:12.706Z  id 5cb0a26bea66fa13786dc289

对我来说，很奇怪的是，我可以在另一个端点（Art）中看到const data = await Art.paginate();模式的所有文档。在那里，我看到了应该匹配的文件

{
   _id: '5cb0a26bea66fa13786dc289',
   title: 'sdfsda'
}

请让我知道是否还有其他细节可以帮助您。
