Mapbox地址解析器仅在获取/创建路径中部分起作用。为什么我的代码无法正常工作？

Question

我正在尝试将地图框地理编码器添加到我的获取/创建路线。我为Geocoder提供了一个异步函数来获取位置的坐标。控制台日志会告诉我对模型坐标的未决承诺，但会在mapbox地理编码功能日志的日志中给我正确的corcordins。从完整阵列的日志。我的代码感觉不错，但是我不明白为什么它不起作用？这是我的代码：

async function geocoder() {
    try {
        let response = await geocodingClient
        .forwardGeocode({
            query: req.body.location,
            limit: 1
        })
        .send()
        var coordinates = response.body.features[0].geometry.coordinates;
        req.body.coordinates = response.body.features[0].geometry.coordinates;
        console.log(response.body.features[0].geometry.coordinates);
        return coordinates
    } catch(err){
        console.log(err.message);
    }
}




// get data from forum and add to post array
var home        = req.body.home;
var title       = req.body.title;
var location    = req.body.location;
var zipcode     = req.body.zipcode;
var coordinates = geocoder(req.body.location);
var dsc         = req.body.description;
var image       = req.body.image;
var endDate     = req.body.endDate
var author      = {
    id:           req.user._id,
    username:     req.user.username
};
var contactInfo = {
    phoneNumber:  formatPhoneNumber(req.body.phoneNumber),
    email:        req.body.email
}

var newHome = {
    data:           data, 
    title:          title,
    location:       location,
    zipcode:        zipcode,
    coordinates:    coordinates, 
    description:    dsc, 
    image:          image, 
    author:         author,
    contactInfo:    contactInfo,
    endDate:        endDate,
};

控制台输出为：

{ coordinates: [ Promise { <pending> } ],
  _id: id,
  service: '10001',
  title: 'Maimi',
  location: 'Miami, Fl',
  zipcode: '33101',
