My openHAB instance stopped working, it shows this:

openhab_1      | null
openhab_1      | Error occurred shutting down framework: java.lang.NumberFormatException: null

Running with this docker-compose.yml

version: '2.2'

services:
  openhab:
    image: "openhab/openhab"
    restart: always
    network_mode: host
    #ports:
    #  - 8086:8086
    #  - 8443:8443
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.openhab.rule=Host(`smart.alwin.kat-zentrale.de`)"
      - "traefik.http.services.openhab.loadbalancer.server.port=8086"
      - "traefik.http.routers.whoami.entrypoints=web"
    volumes:
      - "/etc/localtime:/etc/localtime:ro"
      - "/etc/timezone:/etc/timezone:ro"
      - "openhab_addons:/openhab/addons"
      - "openhab_conf:/openhab/conf"
      - "openhab_userdata:/openhab/userdata"
    environment:
      OPENHAB_HTTP_PORT: "8086"
      OPENHAB_HTTPS_PORT: "8443"
      EXTRA_JAVA_OPTS: "-Duser.timezone=Europe/Berlin"


volumes:
  openhab_addons:

  openhab_conf:
    driver: local
