custom default fallback is not working

[c-akhil]

Description
"utter_default" as text is displaying for end-user,
instead of text set in the bot response for the utter_default

To Reproduce
Steps to reproduce the behavior:

1. Click to 'Responses' in side navigation
2. Click on "Add bot response" button located at top-right
3. Set text in "utter_response_name" as "utter_default"
4. Set any custom fallback text eg:"sorry,what do you mean?" in bot-response-input,
5. Navigate to Stories and train the bot
6. Now chat with bot & Enter some random text for which the bot is not trained
7. Observer the behavior is not modified and "utter_default" is uttered instead of bot-response set
   for it

Expected behavior
custom fallback text set in bot-response-input for utter_default should uttered instead of 'utter_default'

How are you running Botfront? What do the logs (botfront logs) say?

Hi @c-akhil , what fallback policy did you use? Are other responses working as expected or do you get utter-... for everything ? If this is the case the problem is that Rasa can't connect to the NLG server. You can fix that by checkling the logs )botfront logs and fixing the NLG in your endpoints
