Using Gatling Expression Language in Flood.io

Question

I am trying to get my Gatling scala script running in Flood.io. The script uses Gatling EL and works when I am running it locally with gatling-charts-highcharts-bundle-3.7.4

doIf("#{jwtToken.isUndefined()}"){...

But when uploaded to Flood.io I get this error in their logs:

14:37:30.199 [ERROR] i.g.c.action.If - 'if-8' failed to execute: j.l.IllegalArgumentException: For input string: "#{jwtToken.isUndefined()}"

Thanks in advance

[EDIT] Solution found When using the old EL syntax ($ instead of #) I got it running. Furthermore, the Flood.io support needed to set my Gatling version to 3.2 on my Flood.io account.

doIf("${jwtToken.isUndefined()}"){...
