I have a simple scenario, When I want to read the endpoints from the csv file in a circular. The request will be constructed based on the endpoint and same endpoint i need to pass to a function to generate a token and include in the headers.

val scn = scenario("Test").exitBlockOnFail{
    feed(csvFeeder)
    .group("Multiple tests") {
      exec(http("Multiple tests")
        .get("${endpoint}"+request_params)
        .headers(utils.HeaderUtils.create_header("${endpoint}").toMap)
        .check(status.is(200)))
    }.pause(1.seconds)
  }```

The problem is, in the **.get** the **${endpoint}** is replaced with actual value from the csv. But same value tried to pass to a fucntion under **.headers** the actual is not replaced. Its coming as string of ${endpoint} instead of the actual value from csv. 

Can you please suggest here 

Thanks
