Ktor version:3.2.3
If using Proguard (even after applying the rules one can find), calling .body() on a response will throw an exception complaining that it can't find the serializer. Kotlinx serialization itself works fine, I only see the bug when trying to use serialization from a ktor request.
error msg:
kotlinx.serialization.SerializationException: Serializer for class '' is not found.
Please ensure that class is marked as '@serializable' and that the serialization compiler plugin is applied.
