Help with self hosting hive, apollo router and federation v1

[Jasper-ui]

Hi guys, could I ask for a bit of help on this thread, any ideas?

[Jasper-ui]

I'm using Kotlin, my schema gets automatically generated, and this is how my resolver looks like

class PropertyResolver(
    private val control: IApartmentGraphqlControl
) : FederatedTypeSuspendResolver<Property> {
    override val typeName = "Property"
    override suspend fun resolve(
        environment: DataFetchingEnvironment,
        representation: Map<String, Any>
    ): Property? =
        representation["primaryKey"]?.toString()?.let { id -> Property(id, control) }

}

@KeyDirective(FieldSet("primaryKey"))
@ExtendsDirective
data class Property(
    @ExternalDirective val primaryKey: String,
    private val control: IApartmentGraphqlControl
) {
    fun apartments(): List<GraphqlApartmentOutput> = control.findAllApartmentsForProperty(UUID.fromString(primaryKey))

}

also when I try to use Apollo federation V2 I get this:

 Invalid definition for directive @key: argument fields should have type _FieldSet! but found type FieldSet!

Forgot to add @component to the resolver 🤦
