How can i upload image/pdfs in a MERN project using fetch and store them in folder?

Question

I am trying to add new input field to to add files/images in the registration of a user and save the image name in the mongodb and also save image in a folder(of my choice). I am not able to do. I an using client folder for the frontend and server folder for the backend.

this is my code for storing file:

var storage = multer.diskStorage({
    destination : function(req,res,cb){
        cb(null,'public/images')
    },
    filename : function(req,file,cb){
        cb(null, file.fieldname + '-' + Date.now())
    }
})
var upload = multer({dest: storage})

This is my registraion route :

router.post("/register", async(req,res)=>{
    try{
        let picture = (req.file) ? req.file.filename : null ;
        console.log(req.body);
        console.log(picture);
        const {name,email,phone,work,password,cpassword} = req.body;
        const data = new Registration({name,email,phone,work,password,cpassword,picture})
        console.log(data);
        let response = await data.save();
        res.status(200).json({message:"added successfully"});
    }catch(e){
console.log(e)
}})

And this is my front end code:

const postdata= async(e)=>{
    e.preventDefault();
    let url = 'http://localhost:3000/register'
    console.log("===", input.image, "===", input.image.name)
    const formdata = new FormData();
    formdata.append('myimage',input.image,input.image.name )
    formdata.append('name',input.name)
    formdata.append('email',input.email)
    formdata.append('phone',input.phone)
    formdata.append('work',input.work)
    formdata.append('password',input.password)
    formdata.append('cpassword',input.cpassword)

    const response = await axios({
        method: 'post',
    url: url,
    body: formdata,
    headers: {
        'Content-Type': "multipart/form-data",
    },
});
    if(response.status === 200){
          window.alert("added");
          setTimeout(()=>{
            history("/login")
          },1500)
        }
    else{
        window.alert("something went wrong..!");
    }

i have added image property in schema with type: string Now, here the problem is when submit clicked formdata is not passing. console.log(req.body) shows-> {} and console.log(picture) shows-> null

any help?
