NullPointerException using Recorder

I am trying to record a simple Http GET call to a service running locally. I’m running the service on port 8002 and Recorder is listening on 8000, proxying to 8002. Requests are returned to my client (RestClient) as expected but the Recorder does not display anything and I get the error below on the shell.

Thanks for any help.

Hi Greg,

Which version of Gatling do you use?

Regarding the log 15:11:11.697 [ERROR] c.e.e.g.r.c.ConfigurationHelper - No such field com.excilys.ebi.gatling.recorder.configuration.Configuration.resultTypes, it means you’ve been using Gatling 1.0.X, saved your recorder configuration then, and upgraded to 1.1.X. Could you remove your gatling-recorder.ini file located in your home directory, please?
