Simple SDK Request to get DNS Records returns `Missing X-Auth-Key, X-Auth-Email or Authorization headers`

Confirm this is a Python library issue and not an underlying Cloudflare API issue.

• [x] This is an issue with the Python library

Describe the bug

I am just creating a simple client, with the Global API Key and ZoneID to get a list of my DNS records as per the docs: https://developers.cloudflare.com/api/python/resources/dns/subresources/records/methods/list/

However, it returns:

cloudflare.BadRequestError: Error code: 400 - {'success': False, 'errors': [{'code': 9106, 'message': 'Missing X-Auth-Key, X-Auth-Email or Authorization headers'}]}

I've used a both the Global API Key and a custom API Token, with no success. Not sure what I am missing from the documentation.

To Reproduce

Run the following code snippet:

import os
from dotenv import load_dotenv
from cloudflare import Cloudflare

load_dotenv()
CLOUDFLARE_API_KEY = os.environ.get('CLOUDFLARE_API_KEY')
ZONE_ID = os.environ.get('ZONE_ID')

def main():
    client = Cloudflare(
        api_token=CLOUDFLARE_API_KEY,
    )
    page = client.dns.records.list(
        zone_id=ZONE_ID,
    )
    page = page.result[0]
    print(page)


if __name__ == "__main__":
    main()
