Serializing Date Objects Causes Log Not To Emit

When I log datetime objects using Kotlin Logging and drop them into marker KV properties the log simply does not append to the console and appears to silently fail.

import io.github.oshai.kotlinlogging.KotlinLogging
import org.joda.time.DateTime

private val logger = KotlinLogging.logger {}

fun foo() {
  logger.atInfo {
        message = "My message"
        payload = buildMap {
          put("dateKey", DateTime.now().toLocalDate())
        }
      }
}

Errors that occur within logback during encoding/appending can be seen by enabling a logback status listener. This is a logback feature, and not specific to logstash-logback-encoder.

Try enabling the status listener and see if any errors are reported.
