FAQ

Q: In Lab 5: "Programmatically interact with Watson Conversation", I get an authentication error. What do I do?

A: This occurs on Windows. Windows sets the USERNAME variable to the logged in OS user. Ultimately, it ends up overriding the value for USERNAME specified in .env. The problem can be solved in two ways:

on step 3., hard code the USERNAME and PASSWORD e.g.

const conversation = new ConversationV1({
  	username: 'your-username',
  	password: 'your-password',
  	version_date: ConversationV1.VERSION_DATE_2016_09_20
  });

Rename the USERNAME env
- Edit .env, change USERNAME to NP_USERNAME
- in step 3., change USERNAME to NP_USERNAME

import workspace.json file to Watson Conversation tooling not correct

I am following the dw learning course to do the chatbot lab 6. I can successfully import the resources/conversation_workspace.json to Watson Conversation tooling, but when I go to the tooling to see the dialog, there is no response for the #listparks node, so I always get anything_else node response when I input something like "give a list of parks". It's different than the course. Is that correct ? It seems the Watson Conversation tooling has been upgraded so it's not compatible with the old workspace.json ?

Thanks!

Intents to be imported.

Thank you for the developerworks course and this example.
I imported the conversation json in the resources folder as my workspace. That created the intents, entities and dialog flow as well as expected.
I changed the conversation.js in the server code (commented the env) to get this working with IAM_apikey type of authentication and Watson Assistant.The conversation works perfectly. Please see below:

However, there is one issue with the intents as explained below. Please clarify.
When I type "Zion" instead of "Mount Zion" like above, the #tellmeabout intent is not detected. i.e; the response only has in #yes and @Nationalparks detected.
Eventually, in the discoursehandler.js that interprets the response, the default case of the switch case is triggered.
But this somehow results in "park" variable as undefined. Please see below.

Can you tell me the exact intents that you used for your application's (http://nationalparks.mybluemix.net/) workspace ?

I tried the workspace also directly and please find the intents detected.

App seems to be broken?

After cloning and installing on local, when I npm start, the app loads with UI but no "greeting". Also when I type "What parks can you tell me about?" and hit return, nothing appears in app UI and no response either. I have made sure all credentials are correct (username, password, workspace ID, etc).

Lab 5: Authentication Problem on Windows

Hello @cdimascio , I am currently trying to recreate the chatbot, but fail at module 41.

This is my error:

{ Error: Unauthorized: Access is denied due to invalid credentials.
...
code: 401,
error: 'Not Authorized',
description: '2018-05-25T11:14:24-05:00, Error ERCDPLTFRM-DNLKUPERR occurred when accessing https://gateway.watsonplatform.net/conversation/api/v1/workspaces/%3C86181bd0-cf0e-44a2-8eb5-c80bd2c2d5a1%3E/message?version=2016-09-20, Tran-Id: gateway01-59613562 - Invalid UserId and/or Password. Please confirm that your credentials match the end-point you are trying to access. A common error is trying to use credentials from an experimental or beta release against a GA release or vice versa',
body: 'Not Authorized',
'x-global-transaction-id': undefined }

I am very certain that I used the right credentials and workspace id. Is there an issue with the url or the new name of watson conversation to watson assistant? (BTW I do not really have any programming skills).

Thanks in advance!

Critical files required for programmatic calling

Hi @cdimascio,

I came here from your "Chatbots and Watson: Let’s talk about national parks" course, which is really great by the way. It was very difficult to find, but one of the better resources I've come across.

I've started a project from another GitHub repo (the IBM Watson assistant-simple one) and I would like to implement the programmatic calling aspect of this tutorial into that one.

I'm doing this so I can retrieve data from a database like this one allows you to do. I'm just a bit confused about the whole file structure.

What parts would I need to migrate over (as I can't seem to get it to work on my own)? Or do you think it might be better off to start my project over and use this as my base template?

Thanks in advance.
