Hello I'm newbe using traefik:v1.7.18-alpine and I'm getting trouble with ACME.

This is my traefik.toml

debug = false
logLevel = "INFO"

defaultEntryPoints = ["http", "https"]


[accessLog]
  filePath = "access.log"
#  format = "json"


[web]
# Port for the status/dashboard page
address = ":8080"

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

    [entryPoints.https]
    address = ":443"
    [entryPoints.https.tls]

[retry]

[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "localdev.com"
watch = true
exposedByDefault = false

[acme]
email = "myemail@gmail.com"
storage = "acme.json"
entryPoint = "https"
onHostRule = true
    [acme.httpChallenge]
    entryPoint = "http"

This is my docker-compose.yaml

version: '3'

services:
  app:
    image: traefik:v1.7.18-alpine
    restart: always
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    #command:
      # - --acme.storage=acme.json
    
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./traefik.toml:/traefik.toml
      - ./acme.json:/acme.json

With docker-composer up I'm getting this LOGs

As you can see I get "Failed to read new account, ACME data conversion is not available : unexpected end of JSON input" and "Unable to add ACME provider to the providers list: unable to get ACME account : unexpected end of JSON input"

What's I'm doing wrong?
Thanks for answers!
