How to pass or get the value from Map (random generator) to PebbleStringBody in Gatling with Scala

  val names = Iterator.continually {
    Map("name" -> s"PerfTest ${Random.alphanumeric.take(10).mkString}")
  }

.feed(names)
    .exec(http("PerfTest")
      .post("/PerfTest/bulk")
      .body(PebbleStringBody(
       """| [
          |  {% set Iteratecount = 2 %}
          | {% for t in range(1,Iteratecount) %}
          |    {
          |   "name": "{{name}}",    //cannot get the value from feeder :Map or from Json path 
          |   "TestID": "9888988FRFRFDD887887ESES",
          |   "typeId": "9888988FRFRFDD887887ESES",
          |   "statusId": "9888988FRFRFDD887887ESES",
          |   "excludedFromAutoHyperlinking": true
          |    }
          |  {% if loop.last %}
          |  {% else %},{% endif %}
          |  {% endfor %}
          |  ]""".stripMargin)).asJson
      .check(status.is(200))
    )

also could not pass the value from jsonPath to pebbleString body

.check(jsonPath("$.result.name").saveAs("name")

Please help with the solution

I ran your sample (against google.com) with TRACE logging enabled, using Gatling 3.8.4 and it works perfectly fine:

class PebbleSimulation extends Simulation {

  val names = Iterator.continually {
    Map("name" -> s"PerfTest ${Random.alphanumeric.take(10).mkString}")
  }

  val httpProtocol =
    http.baseUrl("https://google.com")
      .acceptHeader("text/html,application/xhtml xml,application/xml;q=0.9,*/*;q=0.8")
      .acceptLanguageHeader("en-US,en;q=0.5")

        "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:16.0) Gecko/20100101 Firefox/16.0"
      )

  val users = scenario("Users")
    .feed(names)
    .exec(http("PerfTest")
      .post("/PerfTest/bulk")
      .body(PebbleStringBody(
        """| [
           |  {% set Iteratecount = 2 %}
           | {% for t in range(1,Iteratecount) %}

           |   "name": "{{name}}",    //cannot get the value from feeder :Map or from Json path

           |    }
           |  {% if loop.last %}
           |  {% else %},{% endif %}
           |  {% endfor %}
           |  ]""".stripMargin)).asJson
      .check(status.is(200))
    )

  setUp(
    users.inject(atOnceUsers(1))
  ).protocols(httpProtocol)
}

Either you're using an old buggy version of Gatling, or your issue is elsewhere.
