Get a value from a CSV Gatling feeder to create a POST request body

I have a pretty simple scenario to get a random value from a CSV file that contains only one column with header id. Then, I want to paste this value into a body of a POST request. An example of the body of my request looks as follows: { "id" : "123" }. So, instead of "123", I need to use a value from a CSV file. Here are my feeder and scenario:

val csvFeeder = csv("src/test/resources/ID.csv").random

val scn = scenario("Test POST request")
  .feed(csvFeeder)
  .exec(http("Test POST request")
    .post(uri)
    .header("Content-type", "application/json")
    .body(StringBody("{\"id\":\"$id\"}"))
    .check(status is 200, responseTimeInMillis lte 2000)
  )

This example is the closest implementation I managed to make so far. But it doesn't work as I expect. I can't paste the value from a feeder into $id that is inside a body(). Currently, Gatling sends the following body: {"id":"$id"}

How can I retrieve a value from a feeder and paste it into a body string request?

Found the solution. The code is right. The issue was in the version of artifact I was using. I used version 3.0.0-RC3 of gatling-charts-highcharts, gatling-core & gatling-http and gatling-maven-plugin was 3.0.0. Now I switched to 2.3.1 for gatling-* dependencies and used 2.2.4 for maven plugin. Now it works.
