我无法从mongoose中获取所有数据。当我尝试获取数据时，它创建了一个新的集合名称（登录），名称为空，但登录集合已经存在。
我不明白我做错了什么
Index.js文件

const express = require("express");
const app = express();
const mongoose = require("mongoose");

mongoose
    .connect("mongodb://0.0.0.0:27017/signin")
    .then(() => console.log("MongoDB Connected"))
    .catch((err) => console.log(err));

const User = require("./models/signin");

app.use("/", (req, res) => {
    User.find({}, (err, data) => {
        if (err) throw new err();
        return res.json(data);
    });
});

app.listen(5500, () => console.log("Port Started on 5500"));

签名

const mongoose = require("mongoose");
const Schema = mongoose.Schema;

const loginSign = new Schema({
    email: { type: String, required: true },
    password: { type: String, required: true },
    date: { type: Date, default: Date.now },
});

module.exports = Users = mongoose.model("signin", loginSign);
