Hello guys. I’m looking for a workaround for an issue https://github.com/Kotlin/kotlinx.serialization/issues/195
Lets say I have a class

@Serializable
data class MyUser(
    val fullName: String,
    val middleName: String? = null,
    val age: Int = 42
)

I want to achieve the result when following object MyUser("John Doe") will lead to json:

{"fullName": "John Doe", age=42}

From what I understand Json(encodeDefaults = false) will disable adding default age. Please give an advice

You can use triple backticks ``` to format the code in a code block.

Or mark the text and choose "Code block"

@elizarov could you help please?

I think you need to annotate with @Transient or @Optional iinm cmiiw @gabin

Out-of-the-box you either have all defaults or none of them. To customize it, you’ll have to write your own serializer for this class or your own JSON format that whould treat nulls in some special way.
