upload using apollo graphql

I am trying to upload user avatars to cloudinary by using apollo graphql.

below is my mutation code:

const cloudinary = require('cloudinary').v2;

module.exports = {

    Mutation: {
        async uploadAvatar(parent, { avatar }, { models, authUser }) {

            const { createReadStream } = await avatar;

            cloudinary.config({

                cloud_name: process.env.CLOUDINARY_CLOUD_NAME,

                api_key: process.env.CLOUDINARY_API_KEY,

                api_secret: process.env.CLOUDINARY_API_SECRET

            });

            try {

                const result = await new Promise((resolve, reject) => {

                    createReadStream().pipe(
                        cloudinary.uploader.upload_stream((error, result) => {
                            if (error) {
                                reject(error);
                            }

                            resolve(result);
                        })
                    )
                });

                await authUser.user.updateOne({ avatar: result.secure_url });

                return authUser.user;

            } catch (error) {
                throw new ApolloError(error);
            }
        }
    }
}
