Hello. The polymorphic serialization of a sealed class is generating this kind of json:

["folder",{"clipFolderId":{"value":"ae5cab51-4336-494f-86c8-e233cebc5467"}}]

instead of something like:

{type:"folder", "clipFolderId":{"value":"ae5cab51-4336-494f-86c8-e233cebc5467"}}

as is described in the documentation. I'm using org.jetbrains.kotlin:kotlin-serialization:1.4.31 and org.jetbrains.kotlinx:kotlinx-serialization-json:1.1.0.
What could be the cause?

Can you share the sealed class?

I'm more interested in the annotations, so you don't have to share the whole thing.

Also, the Json instance you pass to KTor, what are the params you pass to it?
