无法提取地理位置密钥，未知的GeoJSON类型：{坐标：[13.42493130000003，52.50074619999999]

Question

我有此表格可获取用户信息，该用户已正确保存了位置。

但是当我尝试更新它时，它会给我这个错误：

我的用户拥有了我认为需要的所有东西：

const userSchema = new Schema({
  email: {
    type: String,
    unique: true,
    lowercase: true,
    trim: true,
    validate: [validator.isEmail, 'Invalid Email Address'],
    required: 'Please Supply an email address'
  },
  name: {
    type: String,
    required: 'Please supply a name',
    trim: true
  },
  resetPasswordToken: String,
  resetPasswordExpires: Date,
  props: [
    { type: mongoose.Schema.ObjectId, ref: 'User' }
  ],
  // New stuff
  slug: String,
  genres: [String],
  musicLink: String,
  created: {
    type: Date,
    default: Date.now
  },
  location: {
    type: {
      type: String,
      default: 'Point'
    },
    coordinates: [{
      type: Number,
      required: 'You must supply coordinates!'
    }],
    address: {
      type: String,
      required: 'You must supply an address!'
    }
  },
  photo: String,
});

userSchema.index({ location: '2dsphere' })

当我保存它时，有一个控制器仅推送某些内容来更新用户：

exports.updateAccount = async (req, res) => {
  const updates = {
    name: req.body.name,
    email: req.body.email,
    musicLink: req.body.musicLink,
    genres: req.body.tags,
    location: {
      address: req.body.location.address,
      coordinates: [
        req.body.location.coordinates[0],
        req.body.location.coordinates[1],
      ]
    }
  };

  console.log('coordinates: ', updates.location.coordinates)

  const user = await User.findOneAndUpdate(
    { _id: req.user._id },
    { $set: updates },
    { new: true, runValidators: true, context: 'query' }
  );
  req.flash('success', 'Updated the profile!');
  res.redirect('back');
};

任何想法可能是什么问题？

谢谢。

根据Mongoose docs（对于GeoJSON格式，在underlying standard中指定），几何对象必须包含值为

之一的“几何类型”

  

七个区分大小写的字符串：“ Point”，“ MultiPoint”，“ LineString”，   “ MultiLineString”，“ Polygon”，“ MultiPolygon”和“ GeometryCollection”

错误消息

unknown GeoJSON type: { coordinates: [13.42493130000003, 52.50074619999999 ]

引用对象中缺少的type属性。包括type以避免错误：

{type: "Point", coordinates: [13.42493130000003, 52.50074619999999 ]}
