If you encounter an error like "API key not valid. Please pass a valid API key." while chatting with the chatbot, please follow these steps:

1. Go to Google AI Studio.
2. Navigate to the API key section and create a new API key.

Your API key will look something like this: AIzaSyAtpnKGX13bTgmx0l_gQeatYvdWvY_wOTQ

Note: The API is free but has a limited number of usage requests.

1. Open your project folder in VS Code.
2. Locate to the script.js file in your project.
3. Find the API_KEY variable and replace PASTE-YOUR-API-KEY with your actual API key.

1. Save the script.js file after adding your API key.
2. Open index.html in your browser to verify that Chatbot is working correctly.
