Как записать документы в MongoDB, используя транзакции ReactiveMongo?

Я пытаюсь запустить этот простой код, который вставляет документ в коллекцию «отчетов» при транзакции.

Это код: 

def runWithTransaction(): Future[Unit] = {
    for {
      dbWithSession <- db.db.startSession()
      dbWithTx <- dbWithSession.startTransaction(None)

      reportsCollection = dbWithTx.collection[JSONCollection]("reports")
      _ <- reportsCollection.insert.one(BSONDocument("id" -> "123123"))

      _ <- dbWithTx.commitTransaction()
      _ <- dbWithSession.endSession()
    } yield ()
  }

Я получаю следующую ошибку: 

play.api.libs.json.JsResultException: JsResultException(errors:List((,List(JsonValidationError(List(CommandError[code=14, errmsg=BSON field 'OperationSessionInfo.txnNumber' is the wrong type 'int', expected type 'long', doc: {"operationTime":{"$time":1573135213,"$i":1,"$timestamp":{"t":1573135213,"i":1}},"ok":0,"errmsg":"BSON field 'OperationSessionInfo.txnNumber' is the wrong type 'int', expected type 'long'","code":14,"codeName":"TypeMismatch","$clusterTime":{"clusterTime":{"$time":1573135213,"$i":1,"$timestamp":{"t":1573135213,"i":1}},"signature":{"hash":{"$binary":"0000000000000000000000000000000000000000","$type":"00"},"keyId":0}}}]),WrappedArray())))))

Я использую:

  • scala 2.12
  • "org.reactivemongo"% "play2-реактивныйmongo_2.12"% "0.18.8-play27 "
  • MongoDB версия 4.2.1 (фактически это набор реплик с 1 основным)

Любая помощь приветствуется, спасибо.
