Summary
This release improves Event Handler with (a) better serialization error for unsupported data types, and (b) middlewares are now triggered when a route is not found (404). We also crushed OpenAPI bugs for a smoother experience 🪲.
Thanks to @knightmre, Event Source Data Classes now features (a) updates Cognito User Pool User Migration event with verification link, and (b) new Pre-token generation and custom sender events.
🌟 ⭐ A big thank you to our new contributors: @knightmre, @phipag, @keithrozario, and @stevenhoelscher.
Event Handler middlewares are now triggered even when a route is not found (404)
You can now run middlewares even when a route is not found. Before, Event Handler immediately returned a HTTP 404 (Not Found). However, we learned from customers that key middleware logic should always run regardless, hence the fix.
This allows you to consistently perform cross-cutting concerns like logging, header injection, authorization, etc. even for invalid routes.
New CloudFormation Custom Resource Event Source Data Class
You can now use CloudFormationCustomResourceEvent for a better experience with type hinting and code completion support.
NOTE. We recommend customers to use CloudFormation Custom Resource Helper library to author custom resources.
Better error message for unsupported data types in Event Handler
We now raise a SerializationError when trying to serialize unsupported data types. Before, Event Handler did not distinguish between unsupported type or object altogether, like SQLAlchemy models.
You can bring your own custom serializer for additional data type support.
Last but not least, we fixed an issue that occurred when disabling Idempotency using an environment variable. Thanks to @stevenhoelscher for this great catch.
