Need to add FastAPI endpoint by using only gr.mount_gradio_app() method (no demo.launch()), then configure ChatGPT Custom GPT Action with the API endpoint.

Update app.py

Key change: Added demo.launch(server_name="0.0.0.0", server_port=7860) at the end - this keeps the server running!

The issue: Missing launch() call or wrong server setup for Gradio.

Syntax error in the file! There's a typo on line 148

runtime error Better Gradio interface with proper error handling Cleaner layout Examples for testing Proper FastAPI + Gradio mounting
