Gatling setUp Sequential Scenarios

Question

Sequential Scenarios It’s also possible with andThen to chain scenarios so that children scenarios starts once all the users in the parent scenario terminate.

setUp(
  parent.inject(injectionProfile)
    // child1 and child2 will start at the same time when last parent user will terminate
    .andThen(
      child1.inject(injectionProfile)
        // grandChild will start when last child1 user will terminate
        .andThen(grandChild.inject(injectionProfile)),
      child2.inject(injectionProfile)
    )
)

But the code below does not compile:

      setUp(
    scenario("A").inject(atOnceUsers(1))
      .andThen(scenario("B").inject(atOnceUsers(1)))
  )

Compilation error:

     type mismatch;
 found   : io.gatling.core.structure.PopulationBuilder
 required: io.gatling.commons.validation.Validation[io.gatling.core.structure.PopulationBuilder] => ?
      .andThen(scenario("B").inject(atOnceUsers(1)))
                  

             ^

I'm using gatling 3.3.1

Please check the milestone field on the ticket for this feature or the new features list: andThen was introduced in Gatling 3.4.0, so it's not available in Gatling 3.3.1.
