Gatling Feeder - get info from a list

Question

I want to create new Gatling feeder on a list[Strings] from the memory.

In the scenario, I am executing this:

           **.feed(GetGroupIdFeeder.getGroupIdFeed)**

My feeder looks like that:

val getGroupIdFeed : Iterator[Map[String, List[String]]] = { Iterator.continually(Map("groups" -> myList)) }

My list look like that: my_List["a" , "b" , "c"]

in results I am getting :

myList["a" , "b" , "c"] as expected from the feeder...

My expectations is to get from the feeder only "a"

I am aiming that my feeder will be configured as circular.

Details of what I want:

when calling the feeder:

How that can be done?

Any help in this regard would be helpful, thanks!

val getGroupIdFeed = Iterator.continually(List("a", "b", "c"))
  .flatten
  .map(value => Map("groups" -> value))
