Object is not an Enum Error

Description

This error is thrown when applying @strawberry.enum to a non-enum object, for example the following code will throw this error:

import strawberry


# note the lack of @strawberry.enum here:
class NotAnEnum:
    A = "A"


@strawberry.type
class Query:
    field: NotAnEnum


schema = strawberry.Schema(query=Query)

This happens because Strawberry expects all enums to be subclasses of Enum.

How to fix this error

You can fix this error by making sure the class you're applying @strawberry.enum to is a subclass of Enum. For example, the following code will fix this error:

import strawberry


@strawberry.enum
class NotAnEnum:
    A = "A"


@strawberry.type
class Query:
    field: NotAnEnum


schema = strawberry.Schema(query=Query)
