Strawberry GraphQL @ 0.320.2

Released July 6, 2026 at 10:31 AM GMT+00:00

This release fixes a bug where print_schema would emit a type definition twice when the same type (for example an enum) was referenced both as a schema directive field and elsewhere in the schema. The duplicated definition produced invalid SDL that violates the GraphQL spec and is rejected by graphql-core ’s build_schema .

For example, the following schema now prints enum Role only once:

import enum
 
import strawberry
from strawberry.schema_directive import Location
 
 
@strawberry.enum
class Role(enum.Enum):
    EDITOR = "editor"
    VIEWER = "viewer"
 
 
@strawberry.schema_directive(locations=[Location.FIELD_DEFINITION])
class RequiresRole:
    roles: list[Role]
 
 
@strawberry.type
class Query:
    secret: str = strawberry.field(directives=[RequiresRole(roles=[Role.EDITOR])])
 
    @strawberry.field
    def assign(self, role: Role) -> bool:
        return True
