Hey, so maybe someone know why with this code:

@Serializable
data class SerializableTransformation(
  val translateX: Float = 0f,
  val translateY: Float = 0f,
  val rotateY: Float = 0f
)

kotlinx-serialization give me an exception:

Exception in thread "main" kotlinx.serialization.MissingFieldException: Field 'rotateY' is required, but it was missing

I thought that default values make fields optional for serialization, but maybe I'm wrong
Thanks in advance K

create a Json object with a custom configuration:

val nonstrictJson = Json(
        configuration = JsonConfiguration.Stable.copy(ignoreUnknownKeys = true)
    )

[Paul Woitaschek]

@Robert Jaros that's not the solution, the key is known

[Robert Jaros]

@Paul Woitaschek you are probably right, I didn't look close enough at these new config options

[Paul Woitaschek]

That's more for the case where it's really unknown

[Paul Woitaschek]

Ie If the json contained rotateZ
