Hi
i am using

api(platform("io.arrow-kt:arrow-stack:1.2.0-RC"))
api("io.arrow-kt:arrow-core")
api("io.arrow-kt:arrow-core-retrofit")

[Tower Guidev2]

I have requirement where i must access the response HTTP headers returned from my retrofit api calls
so i refactored my return types as follows:-

@Headers(HEADER_ANNOTATION_ACCEPT)
@GET("annotations")
suspend fun annotations(@QueryMap queryParameters: Map<String, String>): ResponseE<CallError, List<Annotation>>

Caused by: kotlinx.serialization.SerializationException: Serializer for class 'CallError' is not found.
