How to use Watson QA REST API

I generated the Question and Answer Service using the following link:

https://developer.ibm.com/mobilefirstplatform/2015/04/29/using-http-adapters-to-access-watson-question-and-answer-service-at-ibm-bluemix/

However, the sample application does not work. The console error says:

[/WatsonQA/apps/services/api/WatsonQA/common/query] exception. TypeError: questionTypes is undefined.

So I tried to get questionType by calling a simple REST API using Postman. I found that calling /v1/services does not result in a response. I received the following message:

No response received

I sent the following method:

(GET) https://gateway.watsonplatform.net/question-and-answer-beta/api/v1/services

I expected the following value: 

{ "services": [ { "overall": 0, "dataset": "", "name": "", "description": "" } ] }

However, a response was not received. How can I fix this problem?

We had an issue in one of our service instance. The call should be working now.

Open a terminal and type

curl -u USERNAME:PASSWORD \
https://gateway.watsonplatform.net/question-and-answer-beta/api/v1/services

Make sure you replace USERNAME and PASSWORD with your service credentials.
