Is there a way to, using the ktor client, handle a response that can be of different type when performing a POST request? I was thinking of using

sealed class

for this but I’m falling short when it comes to supporting the de-serialization of the response. So something like

sealed class ApiResponse

<http://client.post|client.post><ApiResponse> {  }

@Serializable data class ErrorResponse(...) : ApiResponse()

@Serializable data class SuccessResponse(..) : ApiResponse()

Do you use

KotlinxSerializer

? Is it JVM or some other target?

Yes, I’m using `KotlinSerializer`and targeting iOS and Android in MPP

iOS can't acquire serializers via reflection, so you'll have to register all your serializers manually. Also, as far as I'm aware, polymorphic serializer for multi-platform is WIP right now.

Excellent, thank you for pointing me towards this 👍

Glad I could help!
