Hey @Vaishnavishinde9552 , there are a few changes that need to be done:

1. You've used Gemini AI, but OpenAI is also in package.json. Please ensure you remove any irrelevant dependencies.
2. I don't think testEnv.js and dy is needed. If you used it for testing and it was accidentally pushed, please remove it.
3. Do a final check to ensure you haven't made any changes to existing files.

Rest all looks good.

Hi @Annanyatiwary4,
Thank you for the review . I’ve made the requested changes:
Removed OpenAI dependency from package.json since I am using Gemini AI.
Deleted unnecessary test files testEnv.js and dy.
Verified that no existing files were unintentionally modified.

The branch is updated and ready for your review ✅.

@Vaishnavishinde9552, you have added large number of dependencies resulting in changing the entire package.json in frontend and backend , take a look into it. Could you please review these changes and revert to commit f5c84b4? The codebase appeared to be in good working order up to that point. After reverting, please pull the latest changes and retest the pull request.
