Unexcpected token o in JSON at position 1

react-native-cli: 2.0.1
react-native: 0.55.4
"react-native-network-proxy": "^1.0.1",

Proxy is running in the shell


```
import { AppRegistry } from 'react-native';

import App from './src/App';

import { start as startNetworkDebugging } from 'react-native-network-proxy';
startNetworkDebugging();

AppRegistry.registerComponent('EmployeesParkApp', () => App);

```

Reproduce the error with react-native-cli 2.0.1, react-native 0.55.4, and react-native-network-proxy 1.0.1 while the proxy is running. Start from the startNetworkDebugging() entry point shown in the issue, inspect the JSON parsing failure, and confirm that network debugging starts without the reported error.
