我把这个作为我的代码：

import jwt from 'jsonwebtoken';
import { Request, Response } from 'express';
import { JWT_EXPIRY, JWT_SECRET } from '../../config';

interface UserParams {
  username: string,
  password: string
}

interface ReqWithUserParams extends Request {
  user: UserParams
}

const createAuthToken = (user: UserParams): string => {
  return jwt.sign({ user }, JWT_SECRET, {
    subject: user?.username,
    expiresIn: JWT_EXPIRY,
    algorithm: 'HS256'
  });
};

export const login = (req: ReqWithUserParams, res: Response) => {
  const authToken = req.user && createAuthToken(req.user);
  if (authToken) {
    res.json({ authToken });
  } else {
    res.status(401).json({ message: 'Unauthorized' });
  }
};

export const refresh = (req: ReqWithUserParams, res: Response) => {
  const authToken = req.user && createAuthToken(req.user);
  if (authToken) {
    res.json({ authToken });
  } else {
    res.status(401).json({ message: 'Unauthorized' });
  }
};

VSCode中没有类型错误，但是当我运行它时，我得到以下错误：

The last overload gave the following error.
    Argument of type '(req: ReqWithUserParams, res: Response) => void' is not assignable to parameter of type 'RequestHandlerParams<ParamsDictionary, any, any, ParsedQs, Record<string, any>>'.
      Type '(req: ReqWithUserParams, res: Response) => void' is not assignable to type 'RequestHandler<ParamsDictionary, any, any, ParsedQs, Record<string, any>>'.
        Types of parameters 'req' and 'req' are incompatible.
          Type 'Request<ParamsDictionary, any, any, ParsedQs, Record<string, any>>' is not assignable to type 'ReqWithUserParams'.     
            Types of property 'user' are incompatible.
              Type 'User | undefined' is not assignable to type 'UserParams'.
                Type 'undefined' is not assignable to type 'UserParams'.

我如何解决这个问题，为什么会发生这种情况？我假设扩展请求将允许它是可分配的，因为ParamsDictionary的类型看起来就是{ [key:string]: any }
