I'm getting the error: unexpected end of JSON input {"node_id": 0}

When trying to use dens-updater for the first time via this entry in the docker compose file:

  ddns-updater:
    image: qmcgaw/ddns-updater
    container_name: ddns-updater
    networks:
      - default
    ports:
      - 8000:8000/tcp
    volumes:
      - $USERDIR/docker/ddns-updater/data:/updater/data
    environment:
      - DELAY=300s
      - ROOT_URL=/
      - LISTENING_PORT=8000
      - LOG_ENCODING=console
      - LOG_LEVEL=info
      - NODE_ID=0
      - HTTP_TIMEOUT=10s
      - GOTIFY_URL=
      - GOTIFY_TOKEN=
      - PUID=${PUID}
      - PGID=${PGID}
      - TZ=${TZ}
    restart: always

That's most likely because your JSON file is not well formatted. You can check with https://jsonlint.com/

No, this is my JSON below and it is valid:

{
	"settings": [{
			"provider": "cloudflare",
			"domain": "xxx.x",
			"ip_method": "opendns",
			"zone_identifier": "xxxxx",
			"identifier": "xxxxx",
			"host": "x",
			"ttl": 1,
			"token": "xxxxx"
		},
		{
			"provider": "cloudflare",
			"domain": "xxx.x",
			"ip_method": "opendns",
			"zone_identifier": "xxxxx",
			"identifier": "xxxxx",
			"host": "x",
			"ttl": 1,
			"token": "xxxxx"
		}
	]
}

Maybe you have \r characters (windows end of lines literals) in the file?

In config.json ? I don't think so

I'm quite certain it's a problem with the syntax of the file or something not visible like line endings.

Try with

{}

in your file to see if you get the same error. You should get a no settings found error instead.

Have you solved it now? If not, I'll make an alpine based image so you can try debugging it from inside the container.
