Hi Team, I am facing the issue of unsupported media type while executing this below code. Need your help .

code

 def girserviceRoute: Route = path("girservice" / "globalitemrules" / "locationrules" / "v1" / "us" / "Walmart") {
        post {
          entity(as[String]) { reqData =>
            extractRequest { req =>
              log.debug(s"received sbu request, ${req.method} ${req.uri}   ${req.headers} ${req.entity}")
              req.headers.map(x => log.debug(x.name()))
              val hdrs = req.headers.filter(header => (header.isNot("timeout-access") && header.isNot("host")))
              hdrs.map(x => log.debug(x.name()))
              val girServiceUri = s"${girServiceHost}/girservice/globalitemrules/locationrules/v1/us/Walmart"
              val responseFuture = http
                .singleRequest(
                  request = HttpRequest(method = HttpMethods.POST, uri = Uri(girServiceUri).withRawQueryString(req.uri.rawQueryString.getOrElse("")),
                    headers = hdrs,
                    entity = HttpEntity(reqData)),
                  connectionContext = httpsCtx)
                .flatMap(response => response.entity.dataBytes.runReduce(_ ++ _))

              onComplete(responseFuture) {
                case Success(resp) => complete {
                  val st = resp.decodeString(StandardCharsets.UTF_8).replace("5585", "")
                  log.debug("response is " + st)
                  HttpEntity(ContentTypes.`application/json`, st)
                }
                case Failure(ex) => complete {
                  ex.printStackTrace()
                  log.error(ex, ex.getMessage)
                  (StatusCodes.InternalServerError, s"An error occurred: ${ex.getMessage}")
                }
              }
            }
          }
        }
      }

and the Error message Runtime.
