Is there a good way of fixing kotlinx.serialization's handling of nullable values? This class...
```@Serializable
data class MyDataClass(
    val myProp: String?
)```
... will throw `kotlinx.serialization.MissingFieldException: Field 'myProp' is required, but it was missing` if the json does not contain the `myProp` key. I really dont want to add a default value of `null` to every single optional field

Thats a good suggestion, thank you. But honestly its not much better than a null default value.... I guess im looking for a way to set it up during the instantiation of KotlinxSerializer (JsonBuilder)

I feel like defining that the property is nullable should be sufficient for it to be considered optional

looks like you have to provide a default value if that's the behavior you want

<https://github.com/Kotlin/kotlinx.serialization/issues/19> lots of opinions :slightly_smiling_face:

looks like `myProp: String? = null` is the way to go, for better or worse

thats unfortunate but oh well... Thank you!
