我正在做一个使用 typescript 的express项目。我已经设置了控制器和路由器，并有一个方法将我的控制器逻辑 Package 在错误处理程序中。
在我的路由器里。ts文件，post方法会抛出以下错误：

No overload matches this call.
The last overload gave the following error.
Argument of type '(req: Request, res: Response, next: NextFunction) => void' is not assignable to parameter of type 'Application<Record<string, any>>'.

对不起，如果这是一个愚蠢的问题，但我是新的打字和这些类型的错误，我不知道什么是修复。
router.ts

import express from "express";
import { signup } from "../controller/controller.ts";

const authRouter = express.Router();

authRouter.post("/signup", signup);

controller.ts

import { NextFunction, Request ,Response } from "express";
import asyncHandler from "../utils/asyncHandler";

const signup = asyncHandler((req:Request, res:Response, next: NextFunction) => {
    res.status(200).json({ message: "signup" });
});

export { signup };

asyncHandler.ts

import { Request, Response, NextFunction } from "express"

const asyncHandler = (fn:any) => (req: Request, res: Response, next: NextFunction) => {
  Promise.resolve(fn(req, res, next)).catch(next)
}

export default asyncHandler;
