So KMongo for Kotlin is deprecated because of the new official driver (which has been around since 2016)
I’m trying to insert data to the database using an instance of data class that has Instant and LocalDateTime in it
@Serializable
data class User(
val createdAt: Instant,
val updatedAt: Instant,
)
But I’m getting the following exception:
org.bson.codecs.configuration.CodecConfigurationException: Can't find a codec for CodecCacheKey\{clazz=class kotlinx.datetime.Instant, types=null}.

I don’t know how to create a codec for Kotlinx DateTime types and I can’t find one, so can anyone tell me how to do it? thank you for your time and efforts.
the official docs says everything that is Serializable can convert to BSON format in efficient way. is there any chance I’m wrong?
