Property 'base_endpoint' not allowed

The documentation says to set base_endpoint and use the IP.

But I get:
validating /root/docker-compose.yml: services.gerbil additional properties 'base_endpoint' not allowed

I'm not really sure I need it. But Newt gives me:
Failed to connect: failed to get token: failed to get token with status code: 400, body: {"data":null,"success":false,"e

I'm not directly using the Cloudflare VPN. But my network uses DoH (DNS over HTTPS) over Cloudflare.

After setting up a new Newt and creating a new site connecting works now.

But still not sure if I need the base_endpoint if I use DoH.
Because there is another problem:
