How would you properly extend a field on prisma objects

[PatricioNG]

For the sake of this example, let's say I have a prisma Schema which defines this 1:1 relationship via prisma

model Event {
    id              Int           @id @default(autoincrement())
    code            String        @unique
    name            String
    priceMinorUnits Int           @default(0)
    currencyCode    CurrencyCode?
    maxCapacity     Int?

    EventContent     EventContent? //An event can only have one content record (1:1)
}

model EventContent {
    id          Int    @id @default(autoincrement())
    eventID     Int    @unique
    summary     String
    description String
    goodToKnow  String

    Event Event @relation(fields: [eventID], references: [id])
}

And I have a prisma objects defined as this:

const Event = Builder.prismaInterface('Event', {
	name: 'Event',
	
	fields: (t) => ({
		id: t.exposeInt('id', { nullable: false }),
		//...Other fields removed for brevity of example
	}),
});

const PublishedEvent = Builder.prismaObject('Event', {
	name: 'PublishedEvent',
	interfaces: [Event],
	fields: (t) => ({
		content: t.relation('EventContent', { nullable: true }),
	}),
});
const DraftEvent = Builder.prismaObject('Event', {
	name: 'DraftEvent',
	interfaces: [Event],
	fields: (t) => ({
		content: t.relation('EventContent', { nullable: false, onNull: 'error' }),
	}),
});

Why would I be receiving this error:

PothosSchemaError [GraphQLError]: Duplicate field content on Event

As I have only defined it in the objects and not the base interface

You need to use variant instead of name for one of your types if you have multiple objects backed by the same database table

Ah thank you very much!
