Strawberry GraphQL @ 0.334.1

Released October 11, 2026 at 9:35 PM GMT+00:00

This release fixes Strawberry’s rich exception handler crashing with Error in sys.excepthook when a Strawberry error is raised from a script run directly, such as python app.py .

Python 3.13.15+, 3.14.7+ and 3.15 remove __file__ from __main__ before an uncaught exception reaches sys.excepthook , so Strawberry couldn’t find the source of the error. Strawberry now also finds the source file via the module’s spec or loader, and shows the error with its source again.

Errors whose source file is outside the current working directory (for example when running python ../app.py ) are now shown with the file’s absolute path, instead of crashing the handler.

When the source can’t be found at all (for example with python -c or in the REPL), or rendering the error fails for any other reason, Strawberry now falls back to the standard Python traceback.
