node.js - findOneAndUpdate更新数据库但挂起

问题：我的异步函数确实更新了数据库，但是随后的脚本未继续执行。

//Process the data after you get it...
async function burnStatus(data) {
  console.log("Burn Data Compiled Saving...");

  let filter = { _id: "5e4454059a0be1c238b5f70b" };

  if (data.error === true) {
    console.log("Error retrieving burn data.");

    var update = { update: burn.date, error: data.error };
  } else {
    var update = {
      date: data.date,
      precipitation: data.precipitation,
      wind: { morning: data.wind.morning, afternoon: data.wind.afternoon },
      ventIndex: data.ventIndex,
      aqi: data.aqi,
      updated: data.updated
    };
  }

  console.log(update);

  let doc = await BURN.findOneAndUpdate(filter, update, { upsert: true }, (error, result) => {
    // *** NOTHING BELOW HERE EXECUTES EVEN THOUGH THE DB DOES GET UPDATED. ***

    if (error) {
      console.log(error);
    } else {
      console.log(result);
    }
  });

  console.log("Burn Data Updated");
}

这是输出：

Getting Burn Data...
(node:16248) DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.
Response Received Processing...

  ventIndex: 'POOR',
  aqi: 48,
  updated: '2020-02-13T12:42:11.201Z'
}

故障排除：

我设法将其跟踪到let doc = await BURN.findOneAndUpdate(filter, update, (error, result) => {行。我无法获取它引发我要捕获的错误（或者我没有尝试正确捕获该错误）。

所以我猜没有错误，我只是在做错误的事情。

最佳答案

您同时使用await和此处的(error, result)回调

您需要选择一个而不是两者。

等待

try {
  let result = await BURN.findOneAndUpdate(filter, update, {upsert: true});
  console.log("Burn Data Updated")
} catch (error) {
  console.log(error)
}

打回来

let doc = BURN.findOneAndUpdate(
  filter,
  update,
  { upsert: true },
  (error, result) => {
    if (error) {
      console.log(error);
    } else {
      console.log(result);
      console.log("Burn Data Updated");
    }
  }
);
