[GSSoC 2026] Fix #424 - ChatBot not displaying Gemini API responses

[prem-create]

Problem / Issue No: #424

• The chatbot was accepting user input successfully, but Gemini API responses were not being displayed in the UI.

Describe Problem / Root Cause

• After debugging locally, the issue was traced to the Gemini model configuration. The project was using an outdated model:

gemini-1.5-flash-latest

This model is no longer supported for the current Gemini API version, which caused the API request to fail and prevented chatbot responses from appearing.

Solution proposed

• Updated the Gemini model configuration from:

gemini-1.5-flash-latest

to:

gemini-2.5-flash

Additional Information

• Additional works can be done are

add proper try-catch handling for Gemini API exceptions

Add null and empty response checks

Prevent silent chatbot failures

Improve loading/error handling for better debugging and UX
