Strawberry GraphQL @ 0.333.0

Released October 10, 2026 at 5:44 PM GMT+00:00

This release adds an error for input types with fields that have resolvers, raised when the input type is created:

import strawberry
 
 
@strawberry.input
class UserInput:
    name: str
 
    @strawberry.field
    def upper_name(self) -> str:
        return self.name.upper()

Input types only hold the values sent by the client, so the resolver never ran: the schema published upperName: String! as an input field, so requests that left it out failed, and requests that sent it failed with UserInput.__init__() got an unexpected keyword argument 'upper_name' . The same happened to input types inheriting from an output type with resolvers.

Strawberry now raises a ResolverFieldOnInputError pointing at the resolver instead. Remove the resolver, or move the field to an output type.

If you use strawberry-django, update it too: its filter and order methods were fields with resolvers on input types, which [strawberry-django#972 ](https://github.com/strawberry-graphql/strawberry-django/pull/972 ) changes.
