Data Type Error for String Indices

[SemalJohari]

Encountered the following error: 'An error occurred: string indices must be integers, not 'str'', on entering a prompt in the GeetaGPT.
A screenshot to show the error is attached below.
I used Brave Browser on the Microsoft Windows 11 Pro (Version = 10.0.22631 Build 22631) Operating System for running the web application locally.
I installed the required versions of OpenAI and Flask frameworks and it doesn't seem to cause conflicts with the Python version 3.11.7 as of now.
Can you please assign addressing this issue to me, to start off with my contribution in the project? @subh05sus
