找不到play.api.libs.json.jsvalue的编码器

Question

我有这样的案例类，

 case class PrimeraRemoteCopyConfig(
    links: Option[Vector[JsObject]] = None,
    status: Option[Vector[JsObject]] = None,
    targets: Option[Vector[JsObject]] = None,
    groups: Option[Vector[JsObject]] = None,
    groupTargets: Option[Vector[JsObject]] = None,
    groupVolumes: Option[Vector[JsObject]] = None)


object PrimeraRemoteCopyConfig {
    implicit val _format = Json.format[PrimeraRemoteCopyConfig]
}

case class PrimeraConfig(
   systemUid: String,
   tenantId: String,
   systemWWN: String,
    remoteCopyConfig: Option[PrimeraRemoteCopyConfig] = None)

object PrimeraConfig {

  implicit val _format = Json.format[PrimeraConfig]

}

并且使用FlatmapGroupswithState使用状态管理的Spark数据集。

但是，我在线程“ main” java.lang.unsupportedoperationException中得到

 22/05/10 17:07:48 INFO BlockManager: Initialized BlockManager: BlockManagerId(driver, 192.168.0.199, 53277, None)

例外：找不到play.api.libs.json.jsvalue的编码器 - 地图值类：“ play.api.libs.json.jsvalue”

- field (class: "scala.collection.Map", name: "underlying")
- array element class: "play.api.libs.json.JsObject"
- option value class: "scala.collection.immutable.Vector"
- field (class: "scala.Option", name: "links")
- option value class: "model.PrimeraRemoteCopyConfig"

我尝试使用encoders.product.jsobject [jsobject]定义jsobject的编码器，但是它不起作用。我在这里做错了什么
