Dash Button // No device to listen // Cannot read property 'username' of undefined

Hey Guys,
got the following problem on setting up my dash button on homebridge:

After installing the plugin, and updating the Config.json, I got two kind of errors - depending wether I start homebridge with or without sudo.

without sudo:
Error: Error: No devices to listen at create_session (/usr/local/lib/node_modules/homebridge-amazondash/node_modules/node-dash-button/index.js:16:15) at register (/usr/local/lib/node_modules/homebridge-amazondash/node_modules/node-dash-button/index.js:29:24) at DashPlatform.didFinishLaunching (/usr/local/lib/node_modules/homebridge-amazondash/index.js:54:17) at emitNone (events.js:67:13) at API.emit (events.js:166:7) at Server.run (/usr/local/lib/node_modules/homebridge/lib/server.js:90:13) at module.exports (/usr/local/lib/node_modules/homebridge/lib/cli.js:40:10) at Object.<anonymous> (/usr/local/lib/node_modules/homebridge/bin/homebridge:17:22) at Module._compile (module.js:410:26) at Object.Module._extensions..js (module.js:417:10)

with sudo:
TypeError: Cannot read property 'username' of undefined at Server._loadConfig (/usr/local/lib/node_modules/homebridge/lib/server.js:199:31) at new Server (/usr/local/lib/node_modules/homebridge/lib/server.js:49:23) at module.exports (/usr/local/lib/node_modules/homebridge/lib/cli.js:26:16) at Object.<anonymous> (/usr/local/lib/node_modules/homebridge/bin/homebridge:17:22) at Module._compile (module.js:410:26) at Object.Module._extensions..js (module.js:417:10) at Module.load (module.js:344:32) at Function.Module._load (module.js:301:12) at Function.Module.runMain (module.js:442:10) at startup (node.js:136:18)

Homebridge itself seems to work, at least my iphone recognized it and connect it as a new device.

My Config file looks like this:
{
"bridge": {
"name": "Homebridge",
"username": "CC:22:3D:E3:CE:30",
"port": 51826,
"pin": "031-45-154"
},

"platforms":{
"platform": "AmazonDash",
"buttons": [
{
"name": "Dash Blue",
"mac": "mac-adress-of-my-dash"
}
]
}
}

This is strange, homebridge tries to read configuration file and then crashed because there is no username field. Are you sure you placed the config.json in the right place?

I guess so, everytime I changed the parameters in the config file to something strange, I got a complete error of homebridge. Once I undo this, it kind of loads normal again.

this is the path: ~/.homebridge/config.json
