bugstack for Python

Auto-fix AttributeError, KeyError, ImportError, and NoneType errors in Django, Flask, and FastAPI.

What Python Errors bugstack Fixes

AttributeError: 'NoneType' object has no attribute — accessing attributes on None return values
KeyError — accessing missing dictionary keys without .get()
ImportError / ModuleNotFoundError — incorrect import paths or missing modules
TypeError: argument of type 'NoneType' — passing None where a value is expected
ValueError — invalid function arguments and type conversions
Django ORM errors — DoesNotExist, MultipleObjectsReturned, field lookup failures

Install the SDK

Add bugstack to your Python project:

pip install bugstack-sdk

Then initialize it in your application entry point:

import bugstack

bugstack.init(
    api_key=os.environ["BUGSTACK_API_KEY"]
)

Example Fix

bugstack detects an AttributeError caused by calling a method on a None return value and writes a surgical fix:

Before (broken)

def get_user_email(user_id):
    user = db.session.get(User, user_id)
    return user.email

# Runtime error when user is None:
# AttributeError: 'NoneType' object
#   has no attribute 'email'

After (fixed by bugstack)

def get_user_email(user_id):
    user = db.session.get(User, user_id)
    if user is None:
        return None
    return user.email
