Polling Exception - Response body is not valid UTF-8 bytes

Gatling (Open-Source)

Hi, I have an issue while using Gatling Polling. I’m using Gatling 3.3.0

`

private val pollerTokenRefresh = polling.pollerName("TokenRefresh")

val pollerExec = http("[GET] Refresh Token")
  .get("/api/dashboard/v1/token/refresh")
  .headers(
    Map(
      "Accept" -> "application/json, text/plain, */*"
    )
  )
  .check(status.is(200))

val pollerTokenRefreshStart = pollerTokenRefresh.every(5 seconds)
  .exec(
    pollerExec
  )

`

When Polling is sending request to API, there is an empty body in response, which casues an error:

41472 [GatlingSystem-akka.actor.default-dispatcher-5] INFO io.gatling.http.engine.response.DefaultStatsProcessor - Request '[GET] Refresh Token' failed for user 1: i.n.u.IllegalReferenceCountException: refCnt: 0
41472 [GatlingSystem-akka.actor.default-dispatcher-5] ERROR io.gatling.http.response.ByteBufResponseBody - Response body is not valid UTF-8 bytes

But when I do the same request without Polling everything is ok and response has proper body:

body={"status":200,"result":{"token":"eyJhbGciOiJIUzI1NiJ9.eyJleHAiOjE1NzMxMTk1MDksInVzZXJfaWQiOiJmMDE0MGI2MS1iZTk4LTQwMjktOGNiNS0wZmI1OWEwZTFmNWUifQ.dS9iho4xy0MTkWRMOrMupuxS6lDrrxy5ano37bF4xkw","expiration":299178}}

Did anyone had the same issue with Polling?

Thx, Daniel
