Hi! Trying graphql-kotlin for the first time with 3.6.8 and 4.0.0-alpha.7 for a small control plane, and running into trouble with:

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME)
sealed class Command {
	@JsonTypeName("ResetCursorPosition")
	data class ResetCursorPosition(
		val dataSource: String, val position: Instant
	) : Command()
}

which causes a failure in

assertTypeUniqueness

; might I be missing some semi-obvious gotchas with the current implementation? Is it worth trying to minimize to a reproduction case? Otherwise the DX has been great so far.

Hello, I see you have figured out your issue. However if there is some better error message that you think could be helpful, external contributions are always welcome!
