Debugging today

It's 11 PM. The build is broken. You open ChatGPT.

You start typing your architecture. You paste three files. You re-explain the same thing you explained last week. Twenty minutes later, you're still broken.

I have a FastAPI app. The error is in tasks/notifications.py but it's called from services/email.py which imports from db/session.py and the session is shared across Celery workers...

Try wrapping your database call in a try/except block and ensure you're properly closing your session after each request.

You11:14 PM

That didn't work. Here's the full traceback and the three files involved...

AI11:16 PM

Based on the code you shared, it looks like you might need to use SQLAlchemy's scoped_session. Try importing scoped_session from sqlalchemy.orm...

You11:24 PM

We're already using scoped_session. The issue is the session state across Celery tasks. Let me re-explain the architecture...

DebugAI already has your codebase. You never explain anything.

Error to fix in 8 seconds.

How it works

Three steps. Zero context switching.

Step 01

Your codebase, pre-loaded.

The moment you open VS Code, DebugAI indexes your project. Files, imports, call chains — all mapped before any error hits. No setup. No extra steps.

"Just ask your AI" doesn't work when your AI hasn't read your code.
