Avro4S: Error when Deserializing Abstract Data Types (Could not find implicit value for evidence parameter of type FromRecord)

Question

I am using avro4s

https://github.com/sksamuel/avro4s

I wrote this code

  import java.io.ByteArrayOutputStream
  import com.sksamuel.avro4s._

  sealed trait Dibble
  case class Dobble(str: String) extends Dibble
  case class Dabble(dbl: Double) extends Dibble

  case class Drapper(dibble: Dibble)

  val drapperIn = Drapper(Dabble(2.0))
  val bios = new ByteArrayOutputStream
  val avro = AvroOutputStream.binary[Drapper](bios)
  avro.write(drapperIn)
  avro.close()

  val is = AvroInputStream.binary[Drapper](bios.toByteArray)
  val drapperOut = is.iterator().toList.head
  is.close()

  println(drapperIn == drapperOut)

But I get the following error when reading binary data

Error:(18, 47) could not find implicit value for evidence parameter of type com.sksamuel.avro4s.FromRecord[A$A449.this.Drapper] lazy val is = AvroInputStream.binaryDrapper ^ Error:(18, 47) not enough arguments for method binary: (implicit evidence$13: com.sksamuel.avro4s.SchemaFor[A$A449.this.Drapper], implicit evidence$14: com.sksamuel.avro4s.FromRecord[A$A449.this.Drapper])com.sksamuel.avro4s.AvroBinaryInputStream[A$A449.this.Drapper].
