If your code includes createConnetion for some reason (In my case I'm using GridFsStorage), try adding the following to your code:

    options: {
        useUnifiedTopology: true,
    }

just after file, like this:

    const storage = new GridFsStorage({
    url: mongodbUrl,
    file: (req, file) => {
        return new Promise((resolve, reject) => {
            crypto.randomBytes(16, (err, buf) => {
                if (err) {
                    return reject(err);
                }
                const filename = buf.toString('hex') + path.extname(file.originalname);
                const fileInfo = {
                    filename: filename,
                    bucketName: 'uploads'
                };
                resolve(fileInfo);
            });
        });
    },
    options: {
        useUnifiedTopology: true,
    }
})

If your case looks like mine, this will surely solve your issue. Regards
