Assistant not giving proper response

Problem/Motivation

When I ask some follow-up question in the chatbot, it sometimes just gives a single line answer, something like -
Thank you for the question. I will search.
But then it does not give any other response.
An example follow up question:
Which of the above is available in Asia?
An example response:
Thank you for the question. I will search the RAG database for information on engines available in Asia.

It is not doing search based on the previous context.

Steps to reproduce

- Install AI module, configure VDB provider and assistant
- Configure Assistant to use "Session" in "Allow History".
- Talk to chatbot
