Не работает сохранение файлов на сервере: TypeError: Cannot read properties of undefined (reading 'mv')

Почему сервер не может прочитать mv? TypeError: Cannot read properties of undefined (reading 'mv')

import * as uuid from 'uuid';
import * as path from 'path';

class fileService{
saveFile(file){
    try{
        const fileName = uuid.v4()+'.png';
        const filePath = path.resolve('static',fileName);
        file.mv(filePath);
        return fileName;
    }

    catch (e){
        console.log(e)}       

}
}
export default new fileService();

Postman пишет "goodsData validation failed: image: Path image is required."

goodsData:

import mongoose from 'mongoose';

const goodsData = new mongoose.Schema({

    "name":{type:String,required:true},
    "desc":{type:String,required:true},
    "price":{type:Number,required:true},
    "image":{type:String,required:true},
    "full_desc":{type:String,required:true},
    "type_id":{type:String,required:true},
    "stones":{type:String,required:true},
    "metal_id":{type:String,required:true},      
   })

    export default mongoose.model('goodsData', goodsData)

Роутер:

import goodsDataController from "./goodsDataController.js";

const router = new Router()

router.post('/goods_page', goodsDataController.create)

Controller:

import goodService from "./goodService.js"

class goodsDataController{
async create(req,res){
    try{
        
        const createdGood = await goodService.create(req.body)
        res.json(createdGood)
    
    
        } catch(e){
            res.status(500).json(e.message)
    
        }

}

Service:

import fileService from "./fileService.js";
import goodsData from "./goodsData.js";

class goodService{
async create(createdGood,image){
    const fileName=fileService.saveFile(image)
    

    const createdGoodData = await 
    goodsData.create({...createdGood,image:fileName});
    return createdGoodData;
