How to upload picture using Javascript, multer

I tryed to upload picture using javascript with multer but got the err : 'ERR_INVALID_ARG_TYPE' I didn't find any answer on this... Someone can help me ?

This is my code :

const UserModel = require("../models/user.model");
const { uploadErrors } = require("../utils/errors.utils");
const fs = require("fs");
const { promisify } = require("util");
const pipeline = promisify(require("stream").pipeline);

module.exports.uploadProfil = async (req, res) => {
  const MIME_TYPES = {
    "image/jpg": "jpg",
    "image/jpeg": "jpg",
    "image/png": "png",
  };
  try {
    if (!MIME_TYPES) {
      throw Error("invalid file");
    }
    if (req.file.size > 800000) throw Error("max size");
  } catch (err) {
    const errors = uploadErrors(err);
    return res.status(201).json({ errors });
  }

  const fileName = req.body.name + ".jpg";

  await pipeline(
    req.file.stream,
    fs.createWriteStream(
      `${__dirname}/../client/public/uploads/profil/${fileName}`
    )
  );

  try {
    await UserModel.findByIdAndUpdate(
      req.body.userId,
      { $set: { picture: "./uploads/profil/" + fileName } },
      { new: true, upsert: true, setDefaultsOnInsert: true },
      (err, docs) => {
        if (!err) return res.send(docs);
        else return res.status(500).send({ message: err });
      }
    );
  } catch (err) {
    return res.status(500).send({ message: err });
  }
};

And for my route, I have : "router.post("/upload", upload.single("file"), uploadController.uploadProfil);"
