Wrong payload #12

The payload is set to an object but it should be empty. That causes an error in hapijs/h2o2. To reproduce, here is the minimal setup.

package.json

{
  "name": "hapi-h2o2-error",
  "version": "1.0.0",
  "main": "index.js",
  "dependencies": {
    "good": "^7.0.1",
    "good-console": "^6.1.2",
    "good-squeeze": "^4.0.0",
    "h2o2": "^5.1.0",
    "hapi": "^13.5.0",
    "hapi-qs": "^1.1.1"
  }
}

The index.js:

var Hapi = require('hapi');
var server = new Hapi.Server();

server.connection({host: 'localhost', port: 3000});

server.register([
  require('h2o2'),
  require('hapi-qs'),
  {
    register: require('good'),
    options: {
      reporters: {
        console: [{
          module: 'good-squeeze',
          name: 'Squeeze',
          args: [{log: '*', response: '*'}]
        }, {
          module: 'good-console'
        }, 'stdout']
      }
    }
  }
], (error) => {
  if (error) {
    throw error;
  }

  server.route([  {
    method: 'GET',
    path: '/test',
    handler: {
      proxy: {
        passThrough: true,
        mapUri: (request, callback) => {
          callback(null, 'https://api.github.com/users/ro-ka');
        }
      }
    }
  }]);
});

server.start(error => {
  if (error) {
    throw(error);
  }

  server.log('info', `Server running at: ${server.info.uri}`);
});

I installed good for logging. What causes this error is this header: Content-Type: application/x-www-form-urlencoded. So when using curl, this is what happens:

~ – curl 'http://localhost:3000/test' -H 'Content-Type: application/x-www-form-urlencoded'
{"statusCode":500,"error":"Internal Server Error","message":"An internal server error occurred"}

~ – curl 'http://localhost:3000/test'

  "gravatar_id": "",
  "url": "https://api.github.com/users/ro-ka",
  …
}

The error only occurs when the header set. The payload is an empty object which breaks the proxy plugin. Can the payload be set to null or an empty string when there is nothing parsed?
