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 theUSERNAME variable to the logged in OS user. Ultimately, it ends up overriding the value forUSERNAME specified in.env. The problem can be solved in two ways:

• on step 3., hard code theUSERNAME andPASSWORDe.g.

  constconversation=newConversationV1({username:'your-username',password:'your-password',version_date:ConversationV1.VERSION_DATE_2016_09_20});

or

• Rename theUSERNAME env
  • Edit.env, changeUSERNAME toNP_USERNAME
  • in step 3., changeUSERNAME toNP_USERNAME
