fallback topic not triggering

[pavithra8]

Hi All,

We have set up our Virtual agent chatbot with custom topics in our San Diego instance. We have also created our custom fallback set-up topic. The same setup topic is also configured in the 'Conversation Interface > Settings > Virtual Agent > Custom Greetings and Setup > Default Chat Experience > Setup Topics > Fallback' setup topic type.

We want that if the users enters something completely gibberish as an utterance (such as 'sdjkfkhs fsdkhfsjkdfh ksjdfhiosuf isueioursoi fcu439934r') that the VA is not able to predict any intent/topic for, the fallback topic response should get triggered.
However, currently when user enter any gibberish text, the response is the value configured in the system property: 'com.glide.cs.general.retry_question_message'

As we notice from the 'open_nlu_predict_intent_feedback.list' table, the NLU is not predicting any intent or model for the  gibberish utterance.

How can we make the bot respond with the custom fallback response when the user enters a gibberish utterance and no intent/topic is predicted? Any help on this will be very appreciated.
