Node.js TypeError:POINT.find不是mongoose函数

在为mongoose执行Model.find（）时遇到此错误，每个声明看起来都不错。 mongo Atlas中的数据库是

API.js

const mongoose = require("mongoose");

const pointSchema = new mongoose.Schema({
    name: {
        type: String,
        unique: true,
        required: true,
    },
    meridianGroup: {
        type: String,
        required: true,

    sideFacing: { 
        type: String, 
        required: true,
    },
    rightHand: {
        type: Object,
        offX: { 
            type: Number, 
            required: true,
        },
        offY: {

        offY: { 
            type: Number, 
            required: true,

module.export = mongoose.model("point", pointSchema);

以错误的方式导出模型

const router = require("express").Router();
const Point = require("../models/point.model");

// This are are API routes

// Get all points
router.route('/points').get((req, res)=>{
    console.log(Point)
    // res.send("all points")
    Point.find()
        .then(points => res.json(points))
        .catch(err => res.status(400).json(err))
});

module.exports = router;

相反，如果

module.exports = mongoose.model("point", pointSchema);
