How to get output text when using watson conversation api - watson-conversation

Question

I have created a workspace and created the intent, entities and dialogs for a conversation service
Where we use the launch tool and "try it out", i can see the watson text response for the question i asked. But however when i use the api command via a rest client, it does not return the text output.
The input i used for the api was
{
"input": {
"text": "increase the temperature of ac"
}
}
and as response i got the following
{
"input": {
"text": "increase the temperature of ac"
}-
"context": {
"conversation_id": "5a7ce4c2-c6be-4cb8-b728-19136457bf28"
"system": {
"dialog_stack": [1]
0: "root"
-
"dialog_turn_counter": 1
"dialog_request_counter": 1
}-
}-
"entities": [1]
0: {
"entity": "appliance"
"location": [2]
0: 28
1: 30
-
"value": "ac"
}-
-
"intents": [1]
0: {
"intent": "turn_up"
"confidence": 0.9854193755106732
}-
-
"output": {
"log_messages": [0]
"text": [0]
"nodes_visited": [1]
0: "node_1_1469526692057"
-
}-
}
It doesnot have any text message in the json output

Answer 1

This is working as intended.
Using the Github Conversation demo, You can find the related node in the JSON by searching for "conditions": "#turn_up". Here is the related block.
{
"go_to": {
"return": null,
"selector": "condition",
"dialog_node": "node_11_1467233013716"
},
"output": {},
"parent": null,
"context": null,
"created": "2016-07-22T04:55:54.661Z",
"metadata": null,
"conditions": "#turn_up",
"description": null,
"dialog_node": "node_10_1467233003109",
"previous_sibling": "node_7_1467232789215"
},
Alternatively you can look up the block in the Conversation UI looking for #turn_up. For example.
The output field is empty. So the output text is not being handled by Conversation.
It has to be handled at the application layer. There are valid reasons for doing this. For example creating an answer store independent makes it easier for a non-technical user to update. Or if you wanted to hand off to something like Retrieve and Rank to find the answer.
In this case, how the Car demo handles this is detailed in the tutorial video, which you can see here.
