Can not get variable values inside event sourced entity

Hello

I have an event sourced entity (TokenRefreshBaseEntity). When it receives TokenRefreshServiceCommand, it makes a json call using Http().singleRequest. After the response, it should set theProcessResultNewAccessToken, theProcessResultNewRefreshToken values and persist them with some other variables. Although http requests returns respective values of m.access_token and m.refresh_token succesfully, they cannot be assigned to the variables theProcessResultNewAccessToken and theProcessResultNewRefreshToken within oncomplete of the responseFuture. In this link (Request-Level Client-Side API • Akka HTTP), it says if it is an actor then I should use “.pipeTo(self)” But this is not an actor, it is an entity object called from main like : TokenRefreshBaseEntity.init(system)

Can you help me find why I cannot assign values of var values inside the future?

Regards, Ozcan

private def handleCommand(ServiceHandleCommandEntityIdParam: String, state: State, command: Command): ReplyEffect[Event, State] =

log.info(“TokenRefreshAllRefreshedTokensProjectionHandler Pre OK”)

    var theProcessResultNewRefreshToken="EMPTY"

          theProcessResultNewAccessToken="NOTHING"

        .thenReply(replyTo)
        {
