Answer 1

You need to debug your code, but the likely cause is that the returning response you get back is invalid, or no call was made prior to reading the response.

The error:

Fatal TypeError: Cannot read property 'output' of undefined

output is a JSON object that is returned in the response.

Obvious errors

• Service username/password is wrong.
• Workspace ID is wrong.
• URL was not specified if your conversation service is not in the US. Most sample code assumes it runs in the US.
