Fatal TypeError: cannot read property 'output' of undefined

@desmarchris Thanks for this! I was led here by the YouTube video 'Watson Conversation - Integrations Tutorial' However, I am currently running into some issues...

How would you suggest I resolve this?

Thank You

I am receiving the same error. Please advise.

[desmarchris]

can you try taking out the index here? Line 30: bot.reply(message, message.watsonData.output.text[0]);

Hi Chris, great tutorial ! I'm facing the same error. Tried removing the index but it still isn't working.

[desmarchris]

Check if your region is using IAM auth rather than standard username;password as well.. I just added a bit of code to app.js to use if you are using IAM auth (this was @ahendo026 's issue)

[Abishek09]

I'm using the IAM auth.
I made the changes that you've added in the app.js file but I'm still getting the error.
Could there be any other reason for the error?
Thanks for your response!

[desmarchris]

If it's the error above, then the call to Watson is what's not working. Can you share what you are putting in the url parameter? (Note, there aren't any API creds that need to be in the URL)

[Abishek09]

url:'https://gateway-wdc.watsonplatform.net/assistant/api'
This is the URL parameter in my app.js

Here's how the entire code looks:

'use strict'

require('dotenv').config({silent: true});

var middleware = require('botkit-middleware-watson')({
iam_apikey:'6S9SCsbZVqAKiRvCW5Tp4lxPCV6ME6WXwqJFMy0UL24E',
url:'https://gateway-wdc.watsonplatform.net/assistant/api',
workspace_id:'8eb38102-3595-412c-8266-85d9b25a204c',
version:'2018-07-10'
});

var TwilioSMSBot = require('botkit-sms');
var controller = TwilioSMSBot({
account_sid: process.env.ACCOUNT_SID,
auth_token: process.env.AUTH_TOKEN,
twilio_number: process.env.TWILIO_NUMBER
});

let bot = controller.spawn({})

controller.setupWebserver('5500', function (err, webserver) {
if (err) console.log(err)
controller.createWebhookEndpoints(controller.webserver, bot, function () {
console.log('TwilioSMSBot is online!');
})
});

controller.hears(['.*'], 'message_received', function (bot, message) {
middleware.interpret(bot, message, function(err) {
bot.reply(message, message.watsonData.output.text[0]);
})
});

Note: my local server is at port 5500.

@Abishek09 did you run npm update after taking in the IAM code? URL looks fine. Also I would modify that so you aren't sharing your creds :)

@desmarchris Hey Chris,
Thanks for the tutorial. I have a question. How can I send the context variable to the watson with a received message from Twilio? Sorry, I could not find any other communication channel to reach you.
Thanks.
