Cant generate report in gatling 2.2.2

Hi!

When I migrate from 2.1.7 to 2.2.2 my thrift simulation have fold

I redesign my code from Akka to Action includes Chainable to ChainableAction

But I can’t understand what I must use for generate reports

On 2.1.7 I used

DataWriter.dispatch(RequestMessage(

session.scenarioName,…

For 2.2.2 I try to

LogFileDataWriter.ResponseMessageSerializer.serialize(
ResponseMessage(
session.scenario,…

Scenario works fine, but generation fail with

Caused by: java.lang.UnsupportedOperationException: There were no requests sent during the simulation, reports won’t be generated

at io.gatling.charts.report.ReportsGenerator.generateFor(ReportsGenerator.scala:48)

at io.gatling.app.LogFileProcessor.generateReports(RunResultProcessor.scala:64)

at io.gatling.app.LogFileProcessor.processRunResult(RunResultProcessor.scala:43)

at io.gatling.app.Gatling.start(Gatling.scala:66)

Can you help me please?
