Use case

For HTTP resolver, there are few ways to handle exception: https://awslabs.github.io/aws-lambda-powertools-python/2.14.1/core/event_handler/api_gateway/#exception-handling

But for AppSyncResolver, I have no idea who to handle exceptions

Solution/User Experience

Implement @app.exception_handler(ValueError) on the AppSyncResolver.
