【问题描述】:
问题:我的异步函数确实更新了数据库,但没有继续执行脚本的其余部分。
//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...

}
疑难解答:
我已设法将其追踪到let doc = await BURN.findOneAndUpdate(filter, update, (error, result) => { 行。我无法让它抛出一个错误让我捕捉(或者我没有尝试正确捕捉错误)。
所以我猜没有错误,我只是做错了。
