Migrating Traefik version 1 to version 3 - command traefik error: field not found, node: tls

I am currently migrating from Traefik version 1 to Traefik version 3. Here's are my changes

traefik.toml version 1 :

defaultEntryPoints = ["http", "https"]

[web]
address = ":8080"
[web.auth.basic]
users = ["admin:$apr1$kGMbPfo4$wirXXXNT9P5BqkJn1rv8J1"]

[entryPoints]
[entryPoints.http]
address = ":80"
    [entryPoints.http.redirect]
    entryPoint = "https"
[entryPoints.https]
address = ":443"
    [entryPoints.https.tls]
    [[entryPoints.https.tls.certificates]]
        CertFile = "/app/cert.pem"
        KeyFile = "/app/key.pem"
    [[entryPoints.https.tls.certificates]]
        CertFile = "/app/mywebsite.cert.pem"
        KeyFile = "/app/mywebsite.key.pem"

traefik.toml version 3

[entryPoints]
[entryPoints.http]
    address = ":80"
    [entryPoints.http.http.redirections.entryPoint]
    to = "https"

[entryPoints.https]
address = ":443"
[entryPoints.https.tls]
    [[entryPoints.https.tls.certificates]]
    certFile = "/app/mywebsite.cert.pem"
    keyFile = "/app/mywebsite.key.pem"

[api]
dashboard = true
insecure = false

[log]
level = "INFO"

[accessLog]

  traefik:
    networks:
      - proxy
    build:
      context: ./traefik2
      dockerfile: Dockerfile
    command:

      - --providers.docker=true

    restart: always

networks:

However, I am getting error

traefik-1  | {"level":"error","error":"command traefik error: field not found, node: tls","time":"2025-02-28T04:36:16Z","message":"Command error"}

How can I resolve this issue?

Here is the correct traefik.yml for such a purpose.

entryPoints:
  web:
    address: ":80"
    http:
      redirections:
        entryPoint:
          to: websecure
          scheme: https

  websecure:
    address: ":443"
    http:
      tls: {}

tls:
  certificates:
    - certFile: "/app/xxx.me.cert.pem"
      keyFile: "/app/xxx.me.key.pem"
    - certFile: "/app/cert.pem"
      keyFile: "/app/key.pem"

providers:
  docker:
    exposedByDefault: false

log:
  level: INFO

Here's the correct labelling format for each Docker service.

    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.nginx-xxx-email.rule=Host(`email.xxx.me`)"
      - "traefik.http.routers.nginx-xxx-email.entrypoints=websecure"
      - "traefik.http.services.nginx-xxx-email.loadbalancer.server.port=80"
      - "traefik.docker.network=proxy"
