val eventNamesToEmit = mutableListOf<String>()

eventNamesToEmit.addAll(
    node.outgoingLinks
    .filter { it.checkCondition(messageBody) }
    .map { it.eventName }
)

mutable lists should always be questioned:

val eventNamesToEmit = node.outgoingLinks.filter { ... }.map {...}
future.complete(if (eventNamesToEmit.isEmpty()) { ... } else { eventNamesToEmit })

Might be a helper method to shrink that if statement too
