Can't join server with custom dimension

[i1vy]

I'm trying to use a custom dimension with ambientLight(2.0f), but when I try to join the server i get stuck on "Joining world...". I'm getting this error in my client log: java.lang.IllegalStateException: Missing key in ResourceKey[minecraft:root / minecraft:dimension_type]: ResourceKey[minecraft:dimension_type / server:fullbright]

Here's my main function:

val minecraftServer = MinecraftServer.init()
val instanceManager = MinecraftServer.getInstanceManager()

val dimension = DimensionType.builder(NamespaceID.from("server:fullbright"))
    .ambientLight(2.0f)
    .build()

DimensionTypeManager().addDimension(dimension)


val instanceContainer = instanceManager.createInstanceContainer(dimension)

instanceContainer.setGenerator { unit ->
    unit.modifier().fillHeight(0, 40, Block.GRASS_BLOCK)
}


val globalEventHandler = MinecraftServer.getGlobalEventHandler()
globalEventHandler.addListener(
    AsyncPlayerConfigurationEvent::class.java
) { event ->
    val player = event.player
    event.spawningInstance = instanceContainer
    player.respawnPoint = Pos(0.0, 42.0, 0.0)
}


MojangAuth.init()

minecraftServer.start("0.0.0.0", 25565)

Can you try: MinecraftServer.getDimensionTypeManager().addDimension(dimension)
instead of: DimensionTypeManager().addDimension(dimension)
?
