MiddleWare problem

When i deploy the cloud code on parse server i get the following error on log:
Error: Most middleware (like bodyParser) is no longer bundled with Express and must be installed separately. Please see https://github.com/senchalabs/connect#middleware.

No Message provided

I get 'No Message provided' when the webhook is called from the Facebook App. (on line 'console.log(req.body);'

Warning - request header X-Hub-Signature not present or invalid

Using the heroku example results in the issue even though req.headers reveal the following:
'x-hub-signature': 'sha1=XXXXXXXXXXXXXXXXXXXXXXXXXX'

I might however have found the issue:

app.use(bodyParser.json());
app.use(xhub({ algorithm: 'sha1', secret: process.env.APP_SECRET }));

Should be like this according to Express X-Hub README:

app.use(xhub({ algorithm: 'sha1', secret: process.env.APP_SECRET }));
app.use(bodyParser.json());

Because the README specifies that it should be added before bodyParser:

Then add the middleware to Express.js. It needs to be one of the first and before bodyParser().

Bad request

Followed the guide and got following error from facebook webhook validation: The URL couldn't be validated. Callback verification failed with the following errors: HTTP Status Code = 400; HTTP Message = Bad Request
I've deployed using heroku. Any idea?

express deprecated req.param(name)

express deprecated req.param(name): Use req.params, req.body, or req.query instead app.js

how to fix this error?

Signature check

Why there are no X-Hub-Signature check in this examples?

Status code on X-Hub-Signature validation failure

On Getting started document, on section Responding to Event Notifications there is an instruction to always return status 200.

On sample it returns 401 when the token validation fails.

Which one is correct?
