Traefik api basePath seems not works

Traefik Traefik v3 (latest)

I recently tried traefik now
very first, I just use anything else but example
it worked very well.

so I tried one line per try to check any other problem.
it's quite good, but after try basePath, it suddenly get 404

more worse thing is, it's not work even I commented basePath in config, and remove pathprefix from label. (this was just worked before I tried basepath)

# docker-compose
services:
  traefik:
    image: traefik:latest
    container_name: traefik
    secrets:
      - cloudflare_api
    environment:

      - "443:443"
      - "8080:8080"

      - /opt/docker/config/traefik/data/certs:/var/traefik/certs:rw
    networks:
      - proxy
    labels:
      - traefik.enable=true
      - traefik.http.routers.dashboard.rule=Host(`server.domain.test`) && PathPrefix(`/traefik`)

Found solution

if you want to use 'secrets' for token

then you need to use environment name as CF_DNS_TOKEN_API_FILE. document does not mention this, but I found it from youtube.

It is mention in the Traefik LetsEncrypt doc:

Many lego environment variables can be overridden by their respective _FILE counterpart, which should have a filepath to a file that contains the secret as its value. For example, CF_API_EMAIL_FILE=/run/secrets/traefik_cf-api-email could be used to provide a Cloudflare API email address as a Docker secret named traefik_cf-api-email.
For complete details, refer to your provider's Additional configuration link
