Errors in strawberry
Strawberry has built-in errors for when something goes wrong with the creation and usage of the schema.
It also provides a custom exception handler for improving how errors are printed and to make it easier to find the exception source, for example the following code:
import email@example.com Query:@strawberry.fielddef hello_world(self):return "Hello there!"schema = strawberry.Schema(query=Query)
will show the following exception on the command line:
error: Missing annotation for field `hello_world` @ demo.py:7 6 | @strawberry.field ❱ 7 | def hello_world(self): ^^^^^^^^^^^ resolver missing annotation 8 | return "Hello there!"
