Error: Route.get() requires a callback function but got a [object Undefined]

I got the same error (although i can invoke the index.htm in HTML subfolder)
Since router.js has (as shown in the open issue)
var speech_to_text = require('./features/speech_to_text');

then in
speech_to_text,js:

...........................................................
var extend = require('extend');
var watson = require('watson-developer-cloud');
var vcapServices = require('vcap_services');
var config = require('../../env.json');

exports.token = function(req, res) {

}
........................................................................

so would this function(req, res) undefined??

---

Finally I checked out (as shown in error messages above), ZeroToCognitive/Chapter03/controller/restapi/router.js:7:8)

router.get('/api/speech-to-text/token*',speech_to_text.stt_token);

speech_to_text.stt_token should just be: speech_to_text.token
(in speech_to_text function, only exports.token is defined, no stt_token!)

I get to spend extra 1 day in learning node.js and follow the codes!

Following the speech_to_text_complete.js in the answer folder, indeed it uses:

exports.stt_token = function(req, res) {.....................

so follow the speech_to_text_complete.js should also be fine as most of the rest of codes use "stt_token"
