[scala 3] Error deriving JsonReader for simple enum #387
Description
I get error when trying to derive JsonReader for an enum that has opaque type field:
import tethys.*
import tethys.derivation.auto.*
import tethys.derivation.semiauto.*
object Id:
opaque type Id = Long
given JsonReader[Id] = tethys.JsonReader.longReader
object Id:
def apply(i: Long): Id = i
enum Foo(@selector val typ: String) derives JsonReader:
case Bar(id: Id.Id) extends Foo("foo")-- [E007] Type Mismatch Error: -------------------------------------------------
1 |enum Foo(@selector val typ: String) derives JsonReader:

And when Option[Id.Id] is used everything is fine.
