All data mappers do not support JSR310 out of the box, they still use old java date. So, you should search for a codec library that support the new java date/time api (jsr310). Add it as a dependency to your project and configure BSON to use it.

I'm using Kotlinx date time
c
Then you should find a codec for kotlinx instant, maybe there is one around. Otherwise you'll need to implement it yourself.

But Kotlin mongodb driver uses Serializable, should it already support that? because Instant from Kotlinx date time
Can you send me a link of the docs to show how can I create a codec for it?
Or give me basic and simple example?
I found a workaround
c
I'd suggest to check out: https://github.com/agcom/bson

Thanks

Bson serialization format implementation for Kotlinx serialization, based on The BSON library (org.mongodb.bson).
