ERROR empty username

[Lukas8299]

I'm getting the Error ERROR empty username but I followed every step and my config.json looks like this:

{
  "settings": [
    {
      "provider": "ddnss",
      "provider_ip": true,
      "domain": "xxxx.ddnss.de",
      "host": "@",
      "user": "lukas8299",
      "password": "xxxx",
      "ip_version": "ipv4"
    }
  ]
}

try to replace user by username

{
  "settings": [
    {
      "provider": "ddnss",
      "provider_ip": true,
      "domain": "xxxx.ddnss.de",
      "host": "@",
      "username": "lukas8299",
      "password": "xxxx",
      "ip_version": "ipv4"
    }
  ]
}
