Error when deploying to Netlify DNS via Netlify API

I have this JS Code below that creates a subdomain. It deploys it to the Netlify DNS and is successful but it shows the error in the picture below:

fetch('', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer abcdefg-123456-1234-1-123456789'
    body: JSON.stringify({
        'hostname': '',
        'type': 'NETLIFY',
        'value': '',
        'site_id': 'c79d33dc-7dee-4080-ae3a-28932c68eacf'
