Discriminating case classes causes compiler error in Scala 3.1.3 with Tapirs Zio JSON support (Tapir version 1.0.5) #713

I use the following code

sealed trait PositionHint

case class CellPositionHint(
    cellType: CellType,
    mnc: String,
    mcc: String,
    cid: Int,
    lac: Option[Int],
    signalStrength: Option[Int],
    sinr: Option[Int]
) extends PositionHint

object CellPositionHint:
  enum CellType:
    case LTE, GSM, WCDMA, NBIOT, LTEM

case class WlanPositionHint(mac: String) extends PositionHint

case class DeviceLocation(hints: Seq[PositionHint])

and the following Tapir endpoint definition:

val positionInfoEndpoint: PublicEndpoint[DeviceLocation, Unit, GeolocationServiceResult, Any] =
    endpoint.post
      .in("position-info")
      .in(jsonBody[DeviceLocation])
      .out(jsonBody[GeolocationServiceResult])

I get the following compiler error

Sorry, not a ZIO-JSON bug, but a Tapir bug, see https://github.com/softwaremill/tapir/issues/2383
