无法找到此中间件错误的来源

Question

我得到一个中间件不是 function 错误，我不知道为什么......

[Error] TypeError: middleware is not a function

路线 JS

import express from 'express'
import userController from '../../../server/src/controllers/user.controller.js'
import awaitHandlerFactory from '../../../server/src/middleware/awaitHandlerFactory.middleware.js'
export const router = express.Router();
import {auth} from '../middleware/auth.middleware.js'

import { createUserSchema, updateUserSchema, validateLogin } from '../middleware/validators/userValidator.middleware.js'

router.get('/get', auth(), awaitHandlerFactory(userController.getAllUsers))
router.post('/register', createUserSchema, awaitHandlerFactory(userController.createUser))
router.post('/login', validateLogin, awaitHandlerFactory(userController.userLogin))

等待处理程序。

export const awaitHandlerFactory = (middleware) => {
    return async(req, res, next) => {
        try {
            await middleware(req, res, next)
        }
        catch(err)
        {
            next(err)
        }
    }
}

router.post('login') 路由不起作用，其他两个路由都可以正常工作。

这是来自 controller 模块。

    userLogin = async(req, res, next) => {
        this.checkValidation(req)

        const { email, password: pass} = req.body

        const user = await UserModel.findOne({ email })

        if(!user)
        {
            throw new HttpException(401, 'Unable to login.')
        }

        const isMatch = await bcrypt.compare(pass, user.password)

        if (!isMatch) {
            throw new HttpException(401, 'Incorrect password!')
        }

        const secretKey = process.env.SECRET_JWT || ""
        const token = jwt.sign({ user_id: user.id.toString() }, secretKey, {
            expiresIn: '24h'
        })

        const { password, ...userWithoutPassword } = user

        res.send({ ...userWithoutPassword, token})
    }

这是 model 模块

    findOne = async (params) => {
        const {columnSet, values} = multipleColumnSet(params)

        const sql = `SELECT * FROM ${this.tableName} WHERE ${columnSet}`

        const result = await query(sql, [...values])

        return result[0]
    }

验证登录

import { body } from 'express-validator';
import { Role } from '../../utility/userRoles.utility.js';


export const validateLogin = [
    body('email')
        .exists()
        .withMessage('Email is required')
        .isEmail()
        .withMessage('Must be a valid email')
        .normalizeEmail(),
    body('password')
        .exists()
        .withMessage('Password is required')
        .notEmpty()
        .withMessage('Password must be filled')
];

我什至无法指出错误的来源，这是错误的全部内容。

我想通了......几个小时后。 基本上我重写了代码，因为我第一次做了一个凌乱的版本。 出于某种原因，VS-Code 自动将模块从一个完全不同的文件夹链接起来。

根据 ../ 的数量，它会从当前目录进入另一个目录。 这就是为什么我不能使用 userLogin function 因为我在其他版本上没有那么远......

import userController from '../../../server/src/controllers/user.controller.js'
