Hi, We are try to use Taurus do gatling testing, and the yaml look like:

execution:
  - executor: gatling
    scenario: sample
scenarios:
  sample:
    script: build/libs/abc.jar
    simulation: test.TestSimulation

in TestSimilation we use 'io.gatling.javaapi.core.group', code look like:

scenario("ScenarioName")
                .exec(session -> session.setAll(Map.of("timeStamp", nlocalDateTime, "baseUrl", BASE_URL)))
                .group("abc")
                .on(exec(login.doLogin)
                        .exec(access.doAccess).pause(1000, 5000)
                );    

Then we found gatling works fine with result like:

But Taurus get error: ERROR: Child Process Error: Empty results, most likely sample (GatlingExecutor) failed. Actual reason for this can be found in logs under /tmp/artifacts By looking the source code, we can see if we set ".group("abc")" in scenario, the 'req_hierarchy' in below will be always not none and '__parse_request' always return None, could we know if there any reason doesn't support 'req_hierarchy'?

      req_hierarchy = fields[0].split(',')[0]
       if req_hierarchy:
           if error:
               self._group_errors[req_hierarchy].add(error)
           return None
