How to get MS bot to work with Hapi

Question

My current implementation does not return anything useful such as an error message so I am a bit stuck.

method: "POST",
path: '/api/messages',
handler: status

My status function is a simple function:

const status = function (request, reply){  
 return connector.listen(request.raw.req, request.raw.res);
};

also from using the emulator the messages just seem to send and timeout with no log information.

Full code can be seen here

The solution was given to me by Maxpert from the github repo of the Microsoft BotBuilder framework.

<!-- language: lang-js -->
'use strict';

const Hapi = require('hapi');
const botbuilder = require('botbuilder');

const server = new Hapi.Server();
server.connection({ port: 3000 });

/**
 * interface IWebResponse {
 *     end(): this;
 *     send(status: number, body?: any): this;
 *     send(body: any): this;
 *     status(code: number): this;
 * }
 */
function responseWrapper(res) {
    return {
        end() {
            res.end();
            return this;
        },

        send(statusOrBody, maybeBody, callback) {
            var responseCode = 200;
            var responseBody = maybeBody;

            if (typeof statusOrBody == 'number') {
                responseCode = statusOrBody;
                responseBody = maybeBody;
            } else {
                responseBody = statusOrBody;
            }

            if (typeof responseBody != 'string') {
                responseBody = JSON.stringify(responseBody);
            }

            res.writeHead(responseCode);
            res.setHeader("Content-Type", "application/json");
            res.write(responseBody, callback);
            res.end();
            return this;
        },

        status(code) {
            res.writeHead(code);
            return this;
        }
    }
}

/**
 * 
 * interface IWebRequest {
 *     body: any;
 *     headers: {
 *         [name: string]: string;
 *     };
 *     on(event: string, ...args: any[]): void;
 * }
 * 
 */
function requestWrapper(request) {
    return {
        body: request.payload,
        headers: request.headers,
        on(event, listener) {
            request.raw.req.on(event, listener)
            return this;
        }
    }
}

// Initialize your connector
const connector = new botbuilder.ChatConnector({
    appId: 'YOUR APP ID',
    appPassword: 'YOUR APP PASSWORD'
});

const bot = new botbuilder.UniversalBot(connector);
const botHandler = connector.listen();
//=========================================================
// Bots Dialogs
//=========================================================

bot.dialog('/', function (session) {
    session.send("Hello World");
});

server.route({
    method: 'POST',
    path: '/api/messages',
    handler: function (request, reply) {
        var wrappedResponse = responseWrapper(request.raw.res);
        var wrappedRequest = requestWrapper(request);
        botHandler(wrappedRequest, wrappedResponse); // Forwarded!!!
    }
});

server.route({
    method: 'GET',
    path: '/',
    handler: function (request, reply) {
        var req = request.raw.req, 
            res = request.raw.res;
        reply('Hello, world!');
    }
});

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

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