Question

我正在创建一个带有 sequelize 的 api，带有控制器模型迁移...，但是当我将 sucrase 用于导入/导出时，我的 api 损坏了，当我提出请求时，它向我发送了此错误“TypeError：无法读取属性” length' of undefined" ，我被困在这部分，我将在下面留下我的路线/控制器/模型

import express from 'express'
import UserController from './controllers/UserController.js'
const router = express.Router();

const userController = new UserController()

router.post("/users",userController.createUser)
router.post("/login", userController.login)

export default router;

这是我的控制器：

import User from '../models/User.js'
import crypto from 'crypto';
import  Op  from "sequelize";

class UserController {
  async createUser(req, res) {
    const { name, pw, message } = req.body;

    const password = crypto.createHash("md5").update(pw).digest("hex");

    try {
      const user = await User.create({ name, password, message });
      res.status(200).json({
        Response: "usuario criado com sucesso",
      });
    } catch (error) {
      console.log(error)
      res.status(401).json({
        Response: error,
      });
    }
  }

  async login(req, res) {
    const { name, pw } = req.body;
    const password = crypto.createHash("md5").update(pw).digest("hex");

    try {
      const results = await User.findAll({
        attributes: ["message"],
        where: {
          [Op.and]: [{ password: "password" }, { name: "name" }],
        },
      });
      console.log(results);
      res.status(200).json({
        Response: results,
      });
    } catch (error) {
      res.status(401).json({
        Response: "error",
      });
    }
  }
}
export default UserController;

这是我的模型：

import {DataTypes , Model} from 'sequelize';


class User extends Model {
  static init(sequelize) {
    super.init({
      name: DataTypes.STRING,
      password: DataTypes.STRING,
      message: DataTypes.TEXT
    }, {
      sequelize
    });
  }
}
export default User;

在使用 sucrase 之前，我的应用程序运行正常，但是我在导入 dotenv 时遇到了问题，所以我选择使用 sucrase 来帮助我进行导入/导出，值得一提的是，我的迁移运行正常……只有当我要使用 User.create 做一个切口时才会弹出错误，我会将完整的错误消息放在下面，感谢您的关注。

类型错误：无法读取未定义的 Sequelize 模型的属性“长度”
