TypeScript开发MERN项目遇No overload matches this call错误求助

我正在用TypeScript开发MERN栈Web项目，authRoutes.ts的第7行和第10行出现TypeScript类型错误，以下是相关代码和错误详情：

相关代码 #

authRoutes.ts #

import { Router } from "express";
import { register, login } from "./../controllers/authController";

const router = Router();

// Register route
router.post("/register", register);

// Login route
router.post("/login", login);

export default router;

authController.ts #

import { NextFunction, Request, Response } from "express";
import User from "../models/userModel"; // Import the User model

// Register a new user
export const register = async (
  req: Request,
  res: Response,
  next: NextFunction
): Promise<Response> => {
  try {
    const { name, email, password, isAdmin } = req.body;

    // Check if the user already exists
    const userExists = await User.findOne({ email });
    if (userExists) {
      return res.status(400).json({ message: "User already exists" });
    }

    // Create a new user and save to the database
    const user = new User({ name, email, password, isAdmin });
    await user.save();

    return res.status(201).json({ message: "User created successfully" });
  } catch (err) {
    console.error(err);
    return res.status(500).json({ message: "Server error" });
  }
};

// Login user
export const login = async (
  req: Request,
  res: Response,
  next: NextFunction
): Promise<Response> => {
  try {
    const { email, password } = req.body;

    // Find user by email
    const user = await User.findOne({ email });
    if (!user) {
      return res.status(400).json({ message: "Invalid credentials" });
    }

    // Simple password check (no bcrypt for now)
    if (user.password !== password) {
      return res.status(400).json({ message: "Invalid credentials" });
    }

    return res.status(200).json({ message: "Login successful" });
  } catch (err) {
    console.error(err);
    return res.status(500).json({ message: "Server error" });
  }
};

错误信息 #

No overload matches this call.
The last overload gave the following error.
Argument of type '(req: Request, res: Response, next: NextFunction) => Promise' is not assignable to parameter of type 'Application<Record<string, any>>'.
Type '(req: Request<ParamsDictionary, any, any, ParsedQs, Record<string, any>>, res: Response<any, Record<string, any>>, next: NextFunction) => Promise<...>' is missing the following properties from type 'Application<Record<string, any>>': init, defaultConfiguration, engine, set, and 63 more.ts(2769)
index.d.ts(168, 5): The last overload is declared here.

这是我的学习项目，目前对相关知识掌握不足，尝试过一些方法但都无效，请求帮忙解决这个错误。
