我正在上一门Udemy课程，并且尝试推广体验领域。当我这样做时，我得到了错误。我检查了该字段是否确实存在于数据库中并且确实存在。也没有拼写错误，并且我也无法取消移动JSON对象。我按照教程中的每个步骤进行操作，但他在视频中做到了，但我却做不到。
JSON我正在尝试在体验字段上push：
{ "title":"developer",
"company":"mangoo",
"location":"karaikal",
"from":"01-12-2018",
"current":"true",
"description":"developed android app for the firm"
}
https://cdn.datatables.net/1.10.21/js/jquery.dataTables.min.js
router.put('/experience',[
auth,
[check('title','Title is empty').not().isEmpty(),
check('company',"Company name is empty").not().isEmpty(),
check('from','from date is empty').not().isEmpty()]],
async (req,res)=>{
const errors=validationResult(req)
if(!errors.isEmpty()){
return res.status(400).json({errors:errors.array()})
}
const {title,
company,
location,
from,
to,
current,
description
} = req.body
const newExp={
title,
company,
location,
from,
to,
current,
description
}
try {
const profile = Profile.findOne({user:req.user.id})
console.log(profile)
profile.experience.unshift(newExp)
await profile.save()
req.json(profile)
} catch (error) {
console.error(error.message);
res.status(500).json('server error')
}
})

答案 0 :(得分：0)
您忘记添加await关键字：
const profile = await Profile.findOne({user:req.user.id})
