I'm trying to create a user with name, email, password and avatar. the avatar must be uploaded to the cloudninary. after configuring everything, when i tried to upload, i ended up getting this error in my insomnia: "The \"path\" argument must be of type string. Received an instance of Object

here it's my code:

setting up cloudinary

const cloudinary = require('cloudinary');

cloudinary.config({
  cloud_name: process.env.CLOUDINARY_CLOUD_NAME,
  api_key: process.env.CLOUDINARY_CLOUD_KEY,
  api_secret: process.env.CLOUDINARY_API_SECRET,
});

then my register function:

exports.registerUser = catchAsyncErrors(async (request, response, next) => {
  const result = await cloudinary.v2.uploader.upload(request.body.avatar, {
    folder: "avatars",
    width: 150,
    crop: "scale",
  });

  const { name, email, password } = request.body;
  const user = await User.create({
    name,
    email,
    password,
    avatar: {
      public_id: result.public_id,
      url: result.secure_url,
    },
  });

  sendToken(user, 200, response);
});

Edit: if I send a post request with avatar as string, it works normally
