Conversation and Discovery not working

[AlaGarali]

Hello everybody,
I have created the application using this code but conversation and discovery are not working.

1. I have renamed "example.env" file to ".env"
2. I fill out:

Watson conversation

CONVERSATION_USERNAME=<...>
CONVERSATION_PASSWORD=<...>
WORKSPACE_ID=<...>

Watson Discovery

DISCOVERY_USERNAME=<...>
DISCOVERY_PASSWORD=<...>
DISCOVERY_ENVIRONMENT_ID=<...>
DISCOVERY_COLLECTION_ID=<...>
3) I remplaced the workspace.json by a new workspace.json that contain my intents, entities and dialogs
4) npm install
5) npm start
=> the application is running but when typping something, no answer is displayed. For example, when I write "hello" nothing happens.

Please let me know if I have missed any other steps and help me to run this application.

@desmarchris :
Conversation is working but discovery is not working knowing that I have added the discovery intent and questions and in dialog i have discovery dialog node. The extensions of documents uploaded in discovery service are .html and .docs. Please help me to find a solution.
