Python Errors

Python exceptions: ImportError, ModuleNotFoundError, TypeError, ValueError, AttributeError, IndexError, KeyError, FileNotFoundError, ConnectionError, TimeoutError, RecursionError.

Python exceptions inherit from BaseException. Most production issues: ModuleNotFoundError (env mismatch, missing requirements), TypeError on async/await misuse, AttributeError on optional fields, ConnectionError on flaky external services. `pip install` in the wrong venv is responsible for an embarrassing share of ImportError reports.

Configuration (1)

ModuleNotFoundError

No Module Named

The Python interpreter walked `sys.path` and couldn't find the module you imported. Most common cause: you installed the package in a different environment (different venv, different Python version, system pip vs project pip) than the one running your code.
