The Chatbot I created is not displaying user input prompts and results on it. It shows in the cmd though

Question

I created a retrieval Chatbot which works fine with a json file.. The challenge I'm having is retrieving values from a csv file. For example a user wants to retrieve rows/columns with a particular heading. They are supposed to enter a numerical prompt (eg. 1) which searches the dB and returns results based on the item the user wants found. Everything works as planned out but on the cmd.. The results (prompts, outputs) refuse to display on the frontend (flask).

All I want is for the prompts to display on the frontend for user interaction. I've tried different things and no positive results yet . function to search csv file based on columns if, elif to differentiate between columns searches code working fine in cmd nothing from the frontend.
