homebridge: "There was a problem reading your config.json file." Wondering if anybody could help?

Hi, I’m trying to setup Homebridge and am encountering issues, seemingly with the config.json file. Here is my config.json file:

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

"description": "Config file for Xbox.",

"accessories": [
    {
        "accessory": "Xbox",
      "name": "Xbox",
      "ipAddress": "192.168.0.20",
      "liveId": "FD0086CA6C9AF4A6"
    }
]

}

Here is what Terminal is returning when I run Homebridge:
