"Field list is empty" when only using @GraphQLField via deriveContextObjectType

Example:

trait Query {
  val db: Our.Db
  import db._

  @GraphQLField
  def allUsers: Seq[User] = db.run(quote(query[User]))
}

object Query {
  case class Ctx(query: Query)
  implicit val UserOutType = deriveObjectType[Ctx, User]()
  implicit val queryType = deriveContextObjectType[Ctx, Query, Unit](_.query)
  val schema = Schema(queryType)
}

This works just fine if I use:

implicit val queryType =
  deriveContextObjectType[Ctx, Query, Unit](_.query, IncludeMethods("allUsers"))

I’ve tried reading over the macro a time or two but the cause doesn’t jump out at me.

Any ideas?

Have the same issue. Scala 2.12.3. Sangria 1.2.2

interesting fact: looks like annotation with parameters like @GraphQLTags(...) is never missed.
