我在第14行遇到一个错误
请求文件，
错误是：未定义

import { Request, Response } from 'express'
import path from 'path'
import Photo from '../models/Photo';

export function getPhoto(req: Request, res: Response){
}

export async function createPhoto(req: Request, res: Response) {
const {title, description} = req.body;

const newPhoto = {
    title: title,
    description: description,
    imagePath: req.file.path
};

const photo = new Photo(newPhoto);
await photo.save();

    return res.json({
        message: 'Foto creada correctamente',
        photo
    })
}
