Gatling error : Failed to build request: No attribute named 'jwtoken' is defined - scala

Question

I have this error when running my script in scala: "Failed to build request: No attribute named 'jwtoken' is defined " , i extract the value of jwtoken then i put it in a variable, then i want to read it in an other request, i have put 2 objects because i want run two scenario's :
class PPT_GET extends Simulation
{ val httpProtocol = http
.baseUrl("") // Here is the root for all relative URLs
val acteurscsv = csv("./src/test/resources/Data/ksp-acteurs.csv").circular
val jwt = "123"
object TokenGen {
val tokenGen = exec(http("access_token")
.post("https://URL1/token")
.header("Content-Type", "application/x-www-form-urlencoded")
.formParam("grant_type", value = "client_credentials")
.formParam("client_id", value = "PRTAPIPPD")
.formParam("client_secret", value = "xxxxxx")
.check(status is 200, jsonPath("$.access_token").saveAs("atoken")))
.exec(http("jwt_token")
.get("https://bsc-ppd.web.bpifrance.fr/mga/sps/apiauthsvc/policy/AT4JWT")
.header("Authorization", "Bearer ${atoken}")
.header("CorrelationID", "someID")
.header("UsercallerSecret", "user1")
.header("UsercallerID", "X1")
.header("Accept", "application/json")
.check(status is 200, jsonPath("$.JWTFull").saveAs("jwtoken"))) //here i extract the variable jwtoken
}
object Acteurs {
val acteurs =
pause(80)
.feed(acteurscsv)
.exec(http("ksp-acteurs")
.get("https://URL1/ksp-acteurs/${ACTCODE}")
.header("Authorization", "Bearer ${jwtoken}" ) // here where i have the erreor
.check(status is 200))
}

i have put 2 objects because i want run two scenario's
This is not how things work. A scenario is a virtual user journey and data is saved in each virtual user's memory space called Session.
So you can't save data with a check in one scenario and expect to find it in another one, because those scenarios would be executed by different virtual users.
You have to chain your requests in the same scenario, eg:
val scn = scenario("foo").exec(TokenGen.tokenGen, Acteurs.acteurs)
Then, if your goal is to generate one single token for your test, you can use a global reference and sequential scenarios:
var token: String = null
val generateToken = scenario("loadToken")
.exec(TokenGen.tokenGen)
.exec { session =>
token = session("jwtoken").as[String]
session
}
object Acteurs {
val acteurs =
feed(acteurscsv)
.exec(http("ksp-acteurs")
.get("https://URL1/ksp-acteurs/${ACTCODE}")
.header("Authorization", _ => s"Bearer $token" )
.check(status is 200))
}
setUp(
generateToken.inject(atOnceUsers(1))
.andThen(
scenario("acteurs").exec(Acteurs.acteurs).inject(???)
)
)
