Empty response

[shreyashSpark]

Sometimes, empty responses are being displayed on screen.
Agent works completely fine on dialogflow but is problematic here.

Also the intents move forward properly. So in a directional flow conversation, I reply with intended output, it moves to next steps properly. Just not displaying messages.
