Use stored values in another scenerio : Gatling - scala

Question

I want to store returned values from scenerio1 to list and use the same stored values in another scenerio .
I tried to do like below . but in get scenerio this gives error id not found . I also noticed that feeder is initialized before scenerio execution itself.
Could some one please help on this .
var l: List[String] = List()
var ids = l.map(id => Map(“id” -> id)).iterator
val install = scenario(" Install")
.during(Configuration.duration) {
group("installTest") {
exec(
testChain.installApplication()
).exec(session=>{
l = session(“id”).as[String].trim :: l
print(l)
session
})
}
}
val get = scenario(“get”)
.during(Configuration.duration) {
group(“getTest”) {
feed(ids)
exec(
session=>{
print(session(“id”).as[String])
session
}
)
}
}
setUp(
warmupScenario.inject(constantConcurrentUsers(1) during(1))
.andThen(
install.inject(nothingFor(10 seconds), (rampUsers(Configuration.users) during (Configuration.ramp seconds))))
.andThen(
get.inject(nothingFor(Configuration.duration seconds), (rampUsers(Configuration.users) during (Configuration.ramp seconds))))
)
.assertions(details("installTest").successfulRequests.percent.gte(Configuration.passPercentage))
.protocols(HTTP_PROTOCOL)
