Hello,
I’m trying to add logic in my gatling performance script where the scenario is exited when a failure is detected. The way I am exiting the scenario at the moment is by using the session.exit() method. However, doing so I am getting the following error:
`

The sample source code below basically has a web application that simulates a failure past 1000 calls. The idea is that the gatling simulation should stop calling the service, exit and capture the result in the report as a new baseline (as per my previous post https://groups.google.com/d/msgid/gatling/721b9bd0-ad5c-40ac-9526-f8b2b15049c5%40googlegroups.com?utm_medium=email&utm_source=footer)
Is there anything else I should be calling instead of session.exit() to exit make gatling exit the scenario?
