Error when running homebridge

[ollisier]

When I launch homebridge with the plugin installed i get this error:

[2017-12-18 20:13:17] Loaded plugin: homebridge-openhab [2017-12-18 20:13:17] Registering platform 'homebridge-openhab.openHAB' [2017-12-18 20:13:17] --- [2017-12-18 20:13:17] Loaded config.json with 1 accessories and 1 platforms.

this is my config file:

{ "bridge": { "name": "Homebridge", "username": "CC:22:3D:E3:CE:30", "port": 51826, "pin": "031-45-154" },

"description": "",

"accessories": [
    {
    }
],

"platforms": [
    {
    "platform": "openHAB",
    "name": "openHAB",
    "host": "10.0.1.32",
    "port": "8080",
    "sitemap": "home",
    "useLabelForName": true
    }
]

}

Any idea what the problem is?
